Why choose aluminum?

l  Light and soft. The density of aluminum is 2171 g/cm3, which is about a third of the density of steel; Young's modulus is about one third of the steel.

l  Good strength. The tensile strength of pure aluminum is about 80 MN/m2, is one 5 of the low carbon steel. But after heat treatment and alloying strengthening, to achieve the strength of the mild steel corresponding values.

l  Corrosion resistant performance is good. Aluminum alloy is one of the features of air contact surface will form a dense layer of oxide film, the membrane can prevent corrosion, and so the corrosion resistant performance is good. If the implementation of "alumina membrane treatment, can fully prevent the corrosion.

l  Processing performance is good. Railway vehicle use profile extrusion performance is good, the secondary machining, bend more easily also.

l  Easy to regenerate. The low melting point of aluminum (660 ℃), simple regeneration.

       Aluminum alloy is the most widely used in industry of non-ferrous metal structural materials, in aviation, aerospace, automotive, machinery manufacturing, shipping and have been extensively applied in chemical industry.
