Human bodies can excrete small amounts of aluminium very efficiently. This means that minimal exposure to aluminium is not a problem: the World Health Organisation has established a safe daily intake of 40mg per kilogram of body weight per day. So for a person who weighs 60kg the allowable intake would be 2400 mg.
Do experts have something to add to public debate?
But most people are exposed to and ingest far more than this suggested safe daily intake. Aluminium is present in corn, yellow ch

How to choose the right aluminium alloy
|
|
More than 540 registered compositions. I’m talking about the number of aluminium alloys that are available today. Do you know how to choose the one for your product?
Aluminium can be alloyed with other metals and non-metals. This allows the aluminium to take on different properties. Iron (Fe) and silicon (Si) are naturally found in the aluminium, from the bauxite, and are in virtually all technically used aluminium materials.
Aluminium that contains as much as 1 percent by weight, of iron

Does Aluminium get rusted?
|
|
Rust is a type of corrosion (the wearing-away of metal), and to put it simply, aluminium does not rust, but it does corrode. ... As with any metal, when it comes into contact with oxygen, an oxide layer will form on aluminium.
|
|
Which will not rust? Copper, brass,aluminium
|
|
Copper, brass, and bronze do not rust for the same reason as aluminum. All three have a negligible amount of iron in them. Therefore no iron oxide, or rust, can form. However, copper can form a blue-green patina on its surface when exposed to oxygen over time.

Can aluminium stop bullets?
|
|
Aluminum armor can deflect the same rounds from small-caliber weapons as traditional bulletproof glass, but it will still be more clearly transparent even after being shot. Also, a . 50-caliber armor-piercing bullet could sink nearly three inches into bulletproof glass before stopping.

Why is aluminium used to make food containers?
|
|
There are many reasons why aluminium is used to make food containers. Firstly, it's able to withstand both hot and cold temperatures, which means that you can use these containers both in the oven and in your freezer. It's also an affordable material, which means you can stock up on disposable aluminium foil food containers without breaking the bank, and it's a fantastic barrier too. Aluminium will keep your food protected from liquids, gases and light, so it can help your food keep for even lon

What health risks does aluminium intake pose?
|
|
When considering the hazard potential of aluminium, the focus is on effects on the nervous system, on the mental and motor development of children, as well as negative effects on the kidneys and bones.
When aluminium is ingested via food, its acute toxicity is low. In healthy people, most of the aluminium absorbed is excreted via the kidneys. However, in persons suffering from kidney disease, notably chronic renal insufficiency, this excretion process does not work well enough, meaning that a

Why is aluminium contained in food?
|
|
Since aluminium is naturally the third most common element in the earth's crust, it is even found in unprocessed foods. In addition, some aluminium compounds are used as food additives. Additional sources are food packaging and cooking utensils made of aluminium from which aluminium ions can be transferred to food.

I have been assured that it is not harmful, but post-mortem examinations of people who died from or with Alzheimer's have found tangled threads of aluminum in their brains. Researchers say that the threads (called plaques) do not come from food cooked or stored in aluminum, but in that case where did the aluminum come from?
My grandmother and my second mother-in-law both died of Alzheimer's, and they both had used aluminum in their kitchen in many ways. I have enough cards stacked against me

Which windows are better, uPVC or aluminium?
|
|
uPVC or Unplasticized Poly Vinyl Chloride has been a widely used window and door material, across the world, for more than 30 years. uPVC windows are known for their low maintenance and long lasting durability. Of late, uPVC doors and windows have become quite popular with Indian consumers as well.
Aluminium windows, on the other hand, have been present for a long time. They are used widely because of their diverse feature of combining aesthetics with performance.

How do you determine the formula for aluminium hydroxide?
|
|
"Criss-cross" the charges of each atom because it is an ionic compound. This will get you Al(OH)3
Explanation:
Aluminum has a chemical symbol of Al, with a charge of 3+.
Hydroxide is a molecule consisting of two elements - hydrogen and oxygen. The chemical formula for hydroxide is OH1−
.Aluminum is the cation, while hydroxide is the anion, thus we get Al(OH)3
. This is because we still "criss-cross" the charges as it is an ionic compound - electrons are transferred - so aluminum's charge

How woodgrain aluminium provides a superior quality finish
|
|
High quality and upper market wood effect PVCu windows such as the timber look windows such as those available from Residence 9 are exceptional in their appearance and quality. They are an excellent PVCu alternative to a timber look window.
However even what is regarded as the very best in PVCu windows are still foiled. Aluminium windows utilise the very best in powder coating technology to not only create an authentic looking wood effect window but also one that can look better on the insid

What is the more durable woodgrain? Aluminium or PVCu?
|
|
Both woodgrain PVCu and aluminium windows have their respective woodgrain coatings applied in controlled environments that creates a high quality finish. Both types of windows will also come with their respective guarantees that will vary from product to product.
The real test of durability comes if frames are accidentally damaged. Correctly maintained and with routine cleaning both PVCu and aluminium woodgrain products should last and look good for many years to come.

It does not matter if your doors and windows are different brands. Consider allocating more of your budget to premium doors and less to the windows.
Ensure the information provided is factual. There is no ‘bad’ window on the market. Many share specifications and product standards.
It makes sense to have combination windows mixed with doors from the same system. But not essential.
Consider either opening options. Examples include sliding, reversible, opening in, pivoting, tilting and automatic

How aluminium provides effective fire protection offshore
|
|
Aluminium can offer effective protection against fire. This makes it an interesting material for use on offshore installations, such as oil platforms.
The material properties of aluminium are well-documented. Aluminium provides weight savings, when compared with steel, and you get cost savings in installation and maintenance. It is non-combustible and its melting temperature is about 660 °C.
Aluminium loses strength at elevated temperatures before steel does, but some of its properties can

How aluminium is competing with steel on long suspension bridge girders
|
|
Both steel and aluminium are fine materials for bridges. But with suspension bridges, which include girders as structural components, the two materials are apparently not equally fine. No suspension bridges with aluminium girders have ever been built. I will argue that the time is right for change.
Aluminium has been used in bridge structures for nearly a century, starting with the Smithfield Street Bridge in Pittsburgh in 1933. They used a riveted aluminium construction to replace the existi

Why you should use aluminium in icy waters
|
|
Unlike most steel grades, aluminium does not become brittle at low temperatures. Instead, aluminium gets stronger and its ductility and toughness increases. You should know this when you are selecting materials for metal parts to be used in extremely low temperatures.
Allied forces experienced the consequences of poor material selection for a number of the ships built for service during the Second World War. They registered hundreds of significant hull and deck cracks. Twelve broke in half.
