Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards oxygen leads to aluminium's common association with oxygen in nature in the form of oxides; for this reason, aluminium is found on Earth primarily in rocks in the crust, where it is the third-most abundant element, after oxygen and silicon, rather than in the mantle, and virtually never as the free metal. It is obtained industrially by mining bauxite, a sedimentary rock rich in aluminium minerals.
2A12 aluminum shet has high strength, qualified plasticity and poor corrosin resistance. It is mostly used in the state of clad aluminum plate, which is the most widely used duralumin in the aviation industry.
6061 aluminium sheet has good corrosion resistance, weldability and workability. Its machinability makes it the right choice for many extrusion projects because it is easy to shape. Because of good corrosion resistance, it is not only widely used in aviation industry, but also for shipbuilding.
