7 FAST FACTS ABOUT ALUMINIUM :-
1) It Weighs One-Third Less Than Steel
One of the reasons aluminum has become such a widely used metal in the manufacturing industry is because of its lightweight characteristics. On average, aluminum weighs one-third less than steel. If a block of steel weighs 100 pounds, for example, an aluminum block of the same size would weight just 33.3 pounds.
#2) It Doesn’t Rust
Since it doesn’t contain iron, aluminum doesn’t rust. Only metals containing iron, including steel, can rust. This makes aluminum an attractive choice of material for outdoor applications where moisture is a problem. Aluminum products can withstand rain, sleet, snow and humidity without rusting.
#3) It’s the World’s Most Abundant Metal
Consisting of about 8.2% of the Earth’s crust, aluminum is the world’s most abundant metal. Because there’s so much aluminum readily available, it typically costs less than other, less-common metals.
#4) It’s Recyclable
According to the Aluminum Association, it’s the “most recyclable of all materials.” When aluminum is recycled, nearly all of the metal can be reused without creating any waste. And the Aluminum Association notes that recycling just a single aluminum can saves enough energy to power an MP3 player while listening to entire album of songs.
#5) It Was Used Thousands of Years Ago
Some of the first documented uses of aluminum occurred thousands of years ago in Ancient Greece. Back then, people would dye their clothes with alum, which of course, contained aluminum.
#6) It’s Resistant to Heat
While lightweight, aluminum is highly resistant to heat. It will still smelt from a solid to liquid state when exposed to enough heat, but it takes temperatures in excess of 1,220 degrees Fahrenheit to smelt aluminum.
#7) It’s Ductile
Aluminum is a ductile metal that’s easy to bend and shape. Using basic tools and minimal pressure, manufacturing companies can mold aluminum into the necessary shape for their respective applications.

In the process of aluminum sheet shearing, aluminum sheet manufacturers should pay attention to the following points:
1: Scratch phenomenon: Scratch phenomenon is a relatively common phenomenon in domestic shearing. In domestic production of aluminum plate advancing shearing machine, it will rub against the feed port of the shearing machine and cause scratches, which affects the appearance quality of the aluminum sheet . If the user who has high requirements on the quality of the board surface is recommended to be sheared after coating (surface coating, protective aluminum plate), usually the cost of coating is 2 yuan/square meter.
2: The size is accurate: the length and width should be accurate and reasonable, and the diagonal tolerance should be controlled between 1-2mm. Of course, the cutting of small-size aluminum sheet cannot be controlled so precisely.
3: The trimming is neat: the cutting edge of the aluminum sheet is not neat due to the lack of sharpness of the cutting blades of some shears. It is recommended to look for large processing enterprises and new processing equipment during processing. The above points are easy to appear in the cutting process, and the most important is the accuracy of the size.

What are the environmental protection properties of aluminum sheet? Now aluminum sheet has become a common material in decoration. Aluminum sheet has not appeared for a long time, but it can be quickly recognized by consumers. In recent years, we can do it in various occasions. Seeing its existence, then, as one of the new materials, why aluminum plate can become the new darling of decoration materials. Aluminum sheet is an environmentally friendly material among the new materials. Comprehensive advantages in various aspects, aluminum sheet is superior in comparison, so that it is favored by more people. Aluminum sheet is more flexible, easy to shape, and easy to spray and thin. Optional, there are enough series of aluminum plate wholesale products, which can meet any occasions in decoration, whether it is exterior wall decoration, interior decoration, and ceiling, it is very applicable. Aluminum plate products are environmentally friendly materials, no odor, and are also very suitable for small spaces, home decoration, etc., and are also the best choice for decoration materials in special areas such as kitchens and bathrooms. They are safe, healthy, applicable, and have a long service life, and can be printed A variety of colors and patterns to match the decoration style. Two strengthening methods of aluminum plate
Different industries and fields have different performance requirements for aluminum plates. In machining industries, the hardness requirements of aluminum plates are particularly strict. This requires hardening treatment in the production process of aluminum plates to increase the hardness of aluminum plates and meet performance requirements. At present, there are two mainstream processing methods, namely processing strengthening and solid solution strengthening. Aluminum plate manufacturers briefly introduce the two methods: processing strengthened aluminum plates. Processing strengthening is also called cold work hardening, which is the cold deformation processing of aluminum plate below the recrystallization temperature, such as forging, rolling, drawing, stretching, etc. During cold deformation, the internal dislocation density of the aluminum plate increases, and they entangle each other and form a cellular structure , Hinder the movement of dislocations. The greater the degree of deformation, the more serious the dislocation entanglement, the greater the deformation resistance and the higher the strength. The degree of strengthening after cold deformation varies with the degree of deformation, deformation temperature and the properties of the material itself. When the same material is cold deformed at the same temperature, the greater the degree of deformation, the higher the strength and the lower the plasticity.

Flatness of aluminum coil: There is no compound high temperature indentation on the surface of aluminum coil. There is no residual stress on the surface of the aluminum coil, and it is not easy to deform after cutting. The decorativeness of aluminum coil: Because of its good corrosion resistance, sufficient strength, excellent process performance and welding performance, special aluminum plates for architectural decoration are widely used in building frames, doors and windows, ceilings, decorative surfaces, etc. Such as various architectural doors and windows, aluminum profiles for curtain walls, aluminum curtain wall panels, profiled panels, checkered panels, color coated aluminum panels, etc. Weather resistance of aluminum coil: The surface of aluminum and its alloys is easy to form a dense and strong Al2O3 protective film. This protective film can only be destroyed by the intense action of halogen ions or alkali ions. Therefore, aluminum has good resistance to atmospheric (including industrial atmosphere and ocean vapor) corrosion and water corrosion. It can resist the corrosion of most acids and organics, adopts corrosion inhibitors, can resist weak alkali corrosion; adopts protective measures to improve the corrosion resistance of aluminum alloy

Mechanical properties of aluminum coils: use high-quality aluminum, plastics and adhesives, and use advanced composite technology. The product has the required flexural and flexural strength for decorative panels. In the four-season climate, changes in wind pressure, temperature, humidity and other factors will not cause bending, deformation, expansion, etc. Environmental protection of aluminum coil: aluminum coil is corrosion-resistant, strong impact resistance, easy to maintain, resistant to pollution, does not corrode itself to produce toxins, and does not cause any harmful gases, and has strong fire resistance. It is a safe fireproof material. These five characteristics are owned by aluminum coils, and they are also the performance that it has as a building material!
If there are too many impurities inthe aluminum coil, there will be defects in quality after it is made into other products. When the aluminum coil is processed, the oxide layer on the surface of the aluminum coil will be destroyed again, so that the gain is not worth the loss. The aluminum coil is very decorative. When buying, we should not only pay attention to its performance, but also carefully check its appearance. The surface of qualified aluminum coils must not have obvious indentation, missing coating, ripples, scratches, and drums. Bubbles are not allowed. These are easy to see, mainly due to the chromatic aberration of the aluminum coil, if you are not careful, it will affect the decorative effect.

Painting on metal is similar to painting on any other surface. The key difference is how you prepare the surface for painting. Once you clean, sand, and prime aluminum, you can paint it just like you would plastic or wood. The overall process is simple, but it can be time-consuming because you must wait for each layer (primer, paint, and sealer) to dry and cure.

Aluminum is used to make all kinds of everyday items from cars and wheels to refrigerators and kitchenware. It can be polished to make it very shiny, even mirror-like, and is a cheaper alternative to stainless steel and chrome. If you want to get scratches out of something like an aluminum refrigerator, oven, cup, car wheel, bike part, chair, or any other piece of aluminum, try polishing them out. As long as the aluminum doesn’t have any super deep gouges and dents, you can polish out the scuffs and scratches with a few basic supplies and some elbow grease!

| Can aluminum be cut with an abrasive blade cutoff saw? |

You can, but it is messy. I use a Sawzall with a metal cutting blade. Too fine a tooth will plug and melt instead of cut and too coarse will grab and chatter, so use a medium tooth and vary the speed to fit the thickness of the aluminum. The aluminum will clog the abrasive blade, so once you use it for aluminum, do not use it for metal.
