Recycling scrap metal means that we avoid the environmental costs of dumped rubbish and the risk of it leaching toxic chemicals into groundwater at landfill sites. … Recycling also ensures materials don’t become litter! • Reducing the need to dig for virgin materials conserves soil integrity and wildlife habitats.
![[Image: 3g.jpg]](https://www.metalfaq.com/wp-content/uploads/2021/07/3g.jpg) Scrap Metal
Often when we talk about recycling, we think of small-scale household items like plastic bottles and loose paper. But one of the biggest and most important sectors of the recycling industry is scrap metal.
Metals recycling is an established, globally competitive industry that provides essential secondary raw material for metals manufacture, which in turn enables a significant reduction in use of energy and virgin resources.
Metal recycling is common practice, as it uses less energy than metal production. Metal can withstand continual recycling, making it a popular area for companies to survey when conducting their own environmental waste audit. All ferrous metals from iron to stainless steel can be recycled as well as non-ferrous metals such as copper, zinc, and aluminium, making it easy for businesses to bundle scrap metal together for collection.
scrap metal tubes ready for recycling
It is even possible to recover precious metals from computers, like gold, palladium silver and platinum.
Don’t worry, there’s also something in it for you. As well as the excess energy it saves, metal recycling can save your company money. You’ll find that you’ll spend less money on production once you recycle scrap metal rather than reproducing it. In this sense, there’s no reason you shouldn’t start recycling all metal and items containing it, but just for good measure, we’ve listed our top five reasons metal recycling is important.
- To preserve natural resources: Recycling metal substitutes the need to produce virgin metal. In turn, this preserves precious natural resources like coal and iron ore, which are used in the production of metals. As such, recycling metal is seen as an environmental activity — an easy way to take corporate responsibility. Recycling metals also requires less energy than producing new metals. It’s important to give thought to resources like coal. Why? Ten years ago, coal was already beginning to become a climate issue, accounting for 43% of global greenhouse gas emissions. This issue has perpetuated ever since.
- To make the best use of raw materials: Metals is one of the few raw materials that can be readily recycled without damaging its original properties. This means that there isn’t any real reason to create new metal — apart from to meet increased demand. The recycling process can be repeated as many times as needed, even with valuable metals such as aluminium. Scrap metal recycling facilities will always accept a wide range of metals like steel, as operators know that the value of this material will never decrease. Where there’s muck…there’s quite literally brass.
- To offset your company’s carbon emissions: It’s becoming increasingly important for companies to recycle all raw material in attempts to achieve ambitious “zero to landfill” targets. Recycling metal is an environmental alternative to other forms of disposal, as it cuts down emissions and reduces air pollution. By recycling metal, you’re contributing to your business’s carbon goals. Above all, the recycling process will help to eliminate pollution from the atmosphere and encourage others to make the most of metal’s versatile usage.
A tonne of aluminium recycled saved 9 tonnes of CO2 emissions from being released into the atmosphere. The Planet Mark Environmental Foundation confirms that every tonne of aluminium that is recycled results in conserving five tonnes of bauxite.
- To save money by reducing production cost: There’s no shame in recycling as a result of a financial incentive. Most companies recycle on the basis that it’s actually cheaper to do so, allowing you to drive down production cost (and convert this spend into collection costs). It’s much more affordable to utilise the waste that you have by building an effective waste stream than to create natural resources from scratch.
- To meet recycling industry standards: As people grow more concerned about the environment, the recycling industry is putting new pressures on businesses to meet higher recycling standards. Firms are expected to recycle materials where possible, with metal recycling a huge part of this. Needless to say, if you have scrap metal laying around on-site, you should feel obligated to take action. On top of this, the recycling industry benefits the economy by providing employment in waste facilities.
What counts as scrap metal?
Scrap metal is divided into two categories: ferrous and non-ferrous.
Ferrous metals and alloys are generally heavier, stronger materials that contain iron. They include carbon steel, stainless steel, cast iron, and wrought iron, and are often used in housing construction, cars and trucks, and railroads.
Non-ferrous metals include copper, lead, brass, aluminum, tin, zinc, and others. They are among the few materials that do not degrade during the recycling process, meaning they can be recycled an infinite number of times. Non-ferrous metals are lighter and more malleable than ferrous metals.
Why you should recycle scrap metal:
Save energy. The process of recycling metal uses less energy than making brand new metal. This cuts down on greenhouse gas emissions and allocates energy for other purposes, like heating and lighting our homes.
Conserve natural resources. We drastically decrease the burden on our natural resources when we recycle scrap metal. For example, recycling one ton of steel conserves 2,500 pounds of iron ore, 1,400 pounds of coal, and 120 pounds of limestone.
Make MONEY. That’s right; in certain cases you can get paid for your scrap metal. We guarantee the fastest payment in the area, so check with us to see if your materials are eligible.

| Is aluminum metal natural? |

Aluminum is the most common metal found within the earth’s crust (8 percent) but does not occur as a metal in its natural state. Aluminum ore (bauxite) must first be mined then chemically refined through the Bayer process to produce an intermediate product, aluminum oxide (alumina).
Alumina is then refined through the Hall–Héroult process into the pure metal by an electrolytic process. Aluminum is 100 percent recyclable without loss of its properties. Aluminum’s physical properties make the metal light in weight, strong, noncorrosive, nonsparking, nonmagnetic, nontoxic and noncombustible.
Cool Facts
Once, more precious than gold and silver
Before the discovery of the Bayer and Hall–Héroult processes, aluminum was more expensive than gold or silver. Napoleon III served state dinners on aluminum plates.
Aluminum helped pioneer flight
The Wright brothers used aluminum to build key parts of their biplane’s engine because no manufacturer could provide an engine light enough with the needed horsepower.
The lifespan of an aluminum can
A can is recycled over and over again in a true closed loop. Unopened aluminum cans are very strong, despite being so thin. Four six-packs of cans are able to support the weight of a 2-ton vehicle!
Recycling efforts can be improved
Every three months, Americans throw away enough scrap aluminum to rebuild the entire U.S. commercial airplane fleet. Recycling that metal would save the energy equivalent of 16 million barrels of oil.

| What are some Aluminum foil hacks that you apply around the house? |

Aluminum foil is indispensable in the kitchen, whether you put it in the oven to assist the cooking process, or use it to keep leftover food fresher for longer in the fridge.
But what are other uses for your Aluminum foil that makes life easier?
![[Image: aluminiufoil3.jpg]](https://www.metalfaq.com/wp-content/uploads/2021/07/aluminiufoil3.jpg)
Sure, you can make a totally killer robot suit for the kids, or craft something shiny to hustle the birds away from your veggie garden.
Read on to examine different approaches to using Aluminum foil in your kitchen, housework, and cleaning. Chances are you’ll know a few, but hopefully you will find a new idea to work with.
- Cleaning Your Silverware
I can’t believe I never knew aluminum foil causes a chemical reaction that can get rid of the tarnish accrued on your silver and plated silver utensils.
As someone who hates cleaning and polishing flatware (it just never looks good) combining hot water, baking soda and aluminum foil is a game changer.
- Soften Sugar
Have you ever tried to grab the requisite two tablespoons of sugar and had to carve it off with a massive chisel?
A good way to soften your sugar when it’s turned to brick, is wrapping it in foil and sticking it in the oven for a few minutes at 350.
The heat softens up the clumped sugar without melting it, but saves you plenty of elbow grease during recipe prep.
- RFID Card Protection
If you carry the new types of passport, debit or credit card, then chances are it has a Radio Frequency Identification (RFID) chip built in.
While these cards offer more utility and safety than older card types, items with an RFID chip do show some susceptibility to unscrupulous scammers with scanners.
While some people opt for a wallet, purse, or card carrier with RFID protection (my wife bought me one and we didn’t even know) a cheap and effective way to safeguard your cards is to keep them shielded with aluminum foil.
- Clothes Ironing
To be honest, I’m not one for ironing much, it’s one of the perks of working from home (every day can be “say no to pants day” too).
I’ve never been much good at ironing either, however, sticking a sheet of aluminum foil underneath my iron board cover helps get the creases and wrinkles out more effectively than any intensive training I could do.
Aluminum foil reflects heat so sandwiches your clothes nicely, and allows you to get a nice even smoothness on your clothing, without the need for bad language.
- Sharpening Scissors
I generally dislike sharpening scissors, the process lacks the calming capacity that spending time on the whetstone with knives does.
I always treated scissors and shears disposably, picking up a new pair of cheap utensils whenever I felt the need (or lost them).
Nowadays, I sharpen my scissors simply by taking a good length of foil (crinkled then flattened back out is best) and making six or seven full cuts. The resistance from the metal helps hone the blades and keep a nice edge for much longer.
- Cleaning Your Grill
There’s a variety of methods to clean your grill. One of the cheapest and most effective that I have found is using aluminum foil.
The process is simple: scrunch up a big piece of foil into a crinkly ball, then get to work scraping off the soot and detritus from the grill’s cooking surface.
It’s surprising how simple, and how effective the foil is at removing all the rubbish. You should have no need for expensive cleaning products, or brushes and it works for cast iron pots as well (just make sure you don’t use foil on pots with enamel surfaces).
- Fixing a Worn Mirror
If you have an heirloom mirror or bedside table (or live in a rental with a crappy vanity) that has worn in places, it can be a problem.
If a full refinish of the mirror is out of your budget, or if the problem is small, you can create a temporary fix by attaching some tin foil to the back of the glass or unit
I recommend affixing it to the frame with masking tape to the frame so the shiny side goes through. The foil will reflect back as you look at the mirror, minimizing the distraction and making the glass look whole again.
Conclusion
Aluminum foil is tremendous for creating cheap and easy fixes in the home, or for crafting alternative solutions to problems that might pop up

| 5 Things You Should Never Do with Aluminum Foil |

Aluminum foil is endlessly versatile. You can use it to wrap up leftovers, cover a bowl that needs to be stashed in the fridge for a bit, line a baking sheet, clean a pan, and more. You know this. That’s why you, most likely, have a box or three in your home right now. While foil is a great thing to keep around, there are a few things you shouldn’t do with it.
There are a few questionable uses for foil (namely, some people worry about cooking food in foil), but this story is about things you should definitely never do. Here are five things to skip when it comes to your roll of aluminum foil.
1. Don’t put it in the microwave.
This one’s probably the most obvious, but a little reminder can’t hurt — never, under any circumstances, put anything with foil on it in the microwave. Unlike paper or glass, electromagnetic waves can’t pass through metal, so they bounce off — which could result in sparks and flames that could damage your oven or, worse, start fires.
2. Don’t bake cookies on it.
While you can use foil to line a baking sheet for, say, crisping up bacon in the oven, it’s not the best liner for your sheet if you’re making cookies. Lining your cookie sheet with aluminum foil can cause the bottom of your cookies to cook faster, ultimately resulting in uneven bake. Instead, use parchment paper, a silicone baking mat, or a really good nonstick spray.
3. Don’t line the bottom of your oven with it.
In theory, lining the bottom of your oven with aluminum foil as a catch-all for pesky drips and spills is a good idea. In practice, it’s not. Even the folks at Reynolds Wrap say it’s a bad idea: “To avoid possible heat damage to your oven, we do not recommend using aluminum foil to line the bottom of your oven.” Instead, Reynolds says to use a piece of their Heavy Duty foil on the oven rack below whatever you’re baking. (Pull off a length that’s a little longer than the pan you’re using.) This will allow for proper heart circulation and catch any drips.
4. Don’t use it for acidic foods.
Acidic foods (like tomatoes, tomato sauce, and tart fruits) can interact with the aluminum and, after a few days, erode the foil. For these foods, you’re better off using plastic wrap or or even glass containers. Also: If you’re wrapping food up with foil, it’s best for a temporary solution, as a foil-wrapped burrito is not airtight.
5. Don’t toss it after one use.
Aluminum foil can totally be reused if it’s clean enough and not too crumpled. (You can even hand-wash it or put it in the dishwasher on the top rack.) Why not get some extra milage out of the stuff? Also, aluminum foil can almost always be recycled. Check with your town or recycling provider and then do your par

Metal fabrication is generally a straightforward process that involves forming, cutting, and welding. Some materials are tougher to cut than others, so it is important to know what exactly what type of material will be best for the job. When it comes to meeting your fabrication needs, there are many options and a variety of materials to choose from. Depending on the scope and your specific needs for the job aluminum sheet metal may be an ideal and economically viable decision. As we will discuss below there are a variety of benefits when it comes to using aluminum to meet your fabrication needs, while there are many benefits to using aluminum it is not ideal for every job, be sure to consult with a professional if you ever have questions.
Cost Effective
Aluminum is a lightweight metal that is both strong and versatile and can be used in various applications for both indoor and outdoor fabrications such as roofing, gutters, framing, and much more. due to is versatility and relatively low cost when compared to other metals, aluminum is utilized across a variety of industries such as military, aerospace, commercial, and residential. Aluminum sheet metal is great for any contractor looking to minimize their overhead.
![[Image: portoflio-09.jpg]](http://www.aluminium-sheet.com/images/portfolio/portoflio-09.jpg)
Durable
Both plastic and aluminum are on the cheaper end of fabrication quotes, however, if you are looking for a product that is least resistant to wear and tear, aluminum takes the category as well. When it comes to durability aluminum ranks higher than plastic due to its resistance to friction, corrosive elements, and changes in weather, especially high-temperature areas. Under great amounts of heat, plastic has a tendency to warp and melt, whereas aluminum will maintain its shape for years to come.
Corrosion Resistant
Aluminum and steel can be used interchangeably depending on the type of work being conducted, this is another primary reason to opt for aluminum sheet metal over steel mainly due to the fact that aluminum is naturally resistant to corrosion. It is possible to treat steel with a finish to increase its durability, but this will increase the overall cost.

1. Different usage: cold-rolled aluminium plates are mostly used for moulds, and hot-rolled aluminium plates are suitable for stamping and drawing.
2. Different properties: the surface quality of hot-rolled aluminium plates is good, and the mechanical properties and ductility are strong, and the oxidation effect is good. At the same time, the processed aluminium circles are generally processed from aluminium plates, which are naturally affected by the properties of aluminium plates.
3. The supply of raw materials is different: The hot-rolled billet is vertically cast into billet-heated-rolled into coils for cold rolling, and the cold-rolled billet is cast-rolled coil-continuous casting rolling.
4. The production process is different: cold rolling is processed by a casting machine into cast rolls (8mm thickness) and processed by a cold rolling machine, while hot rolling is heated by an aluminium ingot (400-500mm thickness), which is heated at high temperatures, rolled by the hot rolling mill.

Aluminium alloy is a commonly used industrial material. It is very light and weighs about one-third of the same volume of copper or steel. It is corrosion-resistant, is an excellent conductor of heat and electricity, reflects light and radiant heat, is non-magnetic, is not easy to absorb neutrons, can be safely used in food and medicine. And it can be formed into various kinds of industrial materials by all known metal processing techniques. Such as aluminium tube, aluminium circle, aluminium sheet, aluminium foil, aluminium coil, aluminium strip, etc. This article will introduce several common aluminium alloy processing techniques.
(1) Classified according to the force and deformation mode of the product
A. Rolling
Rolling is a deformation process in which the ingot is drawn into the rotating rolls by friction, and with the pressure applied by the rolls, the cross-section is reduced, the shape changes, the thickness becomes thinner and the length increases. According to the different rotation directions of the rolls, rolling can be divided into longitudinal rolling, cross rolling and skew rolling.
During longitudinal rolling, the direction of rotation of the work rolls is opposite, and the longitudinal axis of the rolled piece is perpendicular to the axis of the roll. It is the most commonly used method in flat roll rolling of aluminium alloy plates, strips, and foils.
longitudinal rolling
During cross rolling, the direction of rotation is the same, and the longitudinal axis of the rolling piece is parallel to the axis of the roll, which is rarely used in the rolling of aluminium alloy plate and strip.
Cross rolling
During skew rolling, the rotation direction of the work roll is the same, and the longitudinal axis of the rolling piece is in a certain direction slope. In the production of aluminium alloy pipes and some special-shaped products, two-roll or multi-roll skew-rolling is often used. According to different roll systems, aluminium alloy rolling can be divided into two-roll rolling, multi-roll rolling and special roll rolling (such as planetary rolling, V-shaped rolling, etc.) rolling: according to different roll shapes, aluminium alloy rolling can be divided into flat roll rolling and grooved roll rolling. According to different product varieties, aluminium alloy rolling can be divided into plate, strip, foil rolling, bar, flat bar and special-shaped section rolling, pipe and hollow section rolling, etc.
4. Aluminium tube supplier recommendation
The quality of aluminium tube suppliers on the market is uneven, and the quality and price of aluminium tubes cannot be guaranteed. CHAL Aluminium Corporation is one of the leading aluminium tube suppliers in China. Its products are widely used in the automotive industry, construction industry, HAVC&R and heat transfer industry, aviation, railway transportation, marine industry, etc. Our main aluminium tubes include the following:
