Aluminum can be in the periodic desk of the components, a silvery-white metallic. It is smooth and stretchy but also brittle and hard. Because of its low density is very easy. It is resistant to climate, corrosion and certain acids. Looking at the composition of the earth’s crust, it really is in third place, just after oxygen and silicon. Considering just the proportion of metals, aluminum may be the most abundant element in the earth’s crust with 8%, which is almost twice as much as another iron with just 4.5%.
Similar to stainless steel, when aluminum is subjected to the effects of oxygen, a protective oxide coating forms on the surface of the material, preventing direct connection with moisture and acidic aluminium. Since lightweight aluminum is chemically very reactive, it is very difficult to find it in 100 % pure form. So far, over 270 different minerals have already been found with lightweight aluminum. The primary ore that aluminum is extracted is certainly bauxite – a mixture of nutrients gibbsite (hidrargilite), boehmite and the diaspora, the actual aluminum hydroxide.
Sometimes it is complicated, for the English-speaking area one uses two conditions aluminum and lightweight aluminum. Both conditions refer to the same thing – aluminum, the first is accepted worldwide, as the other is used mainly in the usa and Canada. In Croatia, Glinik is also said for light weight aluminum.
Guangyuan aluminum profile is the most widely used steel after iron. Much like iron, aluminum alloy, which are produced by attaching various other elements, therefore have far better specialized properties than genuine aluminum, and so are also more suitable for the production.
Despite the fact that aluminum is much a lot more than iron, aluminum products are usually more expensive. The difference lies in the complexity of the washing process. Aluminum is obtained solely through electrolysis, which consumes enormous amounts of expensive power. That is one reason why aluminum is more expensive.
Thanks primarily to the precise weight of aluminum, its primary use is found in industries where it is necessary to minimize weight and preserve the essential technical features of steel. As a result, its use is definitely most common in aircraft, space and automotive and it, shipbuilding, beverage and packaging.
It is interesting that light weight aluminum was found out relatively late, at the beginning of the 19th century. In 1855, aluminum was exhibited at the World’s Fair in Paris as something particular. Its silvery shine offered admiration, but the cost was higher then the cost of gold!
