Aluminum is certainly in the periodic table of the elements, a silvery-white metal. It is smooth and stretchy but also brittle and hard. Thanks to its low density is quite easy. It is resistant to weather conditions, corrosion and specific acids. Searching at the composition of the earth’s crust, it really is in third place, just after oxygen and silicon. Considering only the proportion of metals, aluminum is 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 lightweight aluminum is subjected to the consequences of oxygen, a protecting oxide level forms on the top of material, preventing direct connection with moisture and acidic light weight aluminum. Since aluminum is chemically extremely reactive, it is extremely difficult to acquire it in pure form. Up to now, over 270 different minerals have been found with aluminum. The main ore that aluminum is extracted is usually bauxite – a mixture of minerals gibbsite (hidrargilite), boehmite and the diaspora, the actual aluminium hydroxide.
It is sometimes complicated, for the English-speaking area one uses two terms aluminum and aluminium. Both terms refer to a similar thing – aluminum, the first is accepted worldwide, while the other can be used mainly in the United States and Canada. In Croatia, Glinik is also said for lightweight aluminum.
Aluminium Profile Manufacturer is the most widely used steel after iron. Much like iron, aluminium alloy, which are formed by attaching various other elements, therefore have far better technical properties than 100 % pure aluminum, and are also more suitable for the production.
Despite the fact that aluminum is much more than iron, aluminum products are usually more expensive. The difference is based on the complexity of the cleaning process. Aluminum is obtained exclusively through electrolysis, which consumes enormous amounts of expensive power. That is one reason why aluminum is more costly.
Thanks generally to the specific weight of aluminium, its primary make use of is found in industries where it is necessary to minimize pounds and preserve the essential technical features of steel. Therefore, its use is most common in aircraft, space and automotive and it, shipbuilding, beverage and product packaging.
It is interesting that aluminum was uncovered relatively late, at the beginning of the 19th century. In 1855, aluminum was exhibited at the World’s Fair in Paris as something special. Its silvery shine supplied admiration, but the cost was higher then your price of gold!
