What is Aluminum?

Aluminum (Aluminium) – a silver-white, soft metal, noted for lightness, high reflectivity, high thermal conductivity, high electrical conductivity, nontoxicity, and corrosion resistance. Aluminum is the most abundant metallic element, comprising 1/12th of the earth’s crust. However, it is never found in nature as an elemental metal but only combined with oxygen and other elements. In ordinary language, aluminum often means aluminum alloy.

Among all kind of metal materials, aluminum wins out either because its properties and performance are superior or because fabrication techniques enable the finished product to be manufactured at a competitive cost. The usage of aluminum continues to increase and expand; new markets such as the automotive sector are beginning to recognize its true unparalleled benefits. 


In the alloying furnace, the aluminum ingot is melted, and mixed with alloying metals like Magnesium, silica, copper, etc to form a aluminum alloy which offer a wide range of specific material properties. The physical properties of the alloy are very much determined by the alloy content.


Alumina has to go through smelting and alloying processes to become aluminum of common use. An aluminum smelter contains a cryolite bath (in which the mineral cryolite is melted using electrical current). Alumina, in powder form, is placed into the cryolite bath, where it is melted and separated from its oxygen component, settling beneath the cryolite. The molten aluminum is siphoned from the bottom of the smelter and placed in a crucible, then formed into ingot or transferred to an alloying furnace.

Where and how to get aluminum

Bauxite, a mineral mined from the earth is the major source of aluminum. The bauxite is crushed and sprayed with water, clay and silica removed, and then kiln-dried, and mixed with soda ash and crushed lime. The mixture is then processed in a digester, then reduced under pressure and sent to a settling tank where additional impurities are removed.
After filtering, cooling, and further processing in a precipitator, the mixture is thickened and filtered once more before being heated in a calcinating kiln. The resultant material is alumina, a powdery chemical combination of oxygen and aluminum.
