What are the advantages of aluminum alloy material

1, light and soft. Aluminium has a density of 2171g/ cm3, about a third of that of steel; Young's modulus is also about one third of that of steel.

2. Good strength. The tensile strength of pure aluminum is one-fifth that of mild steel. But after heat treatment and alloying strengthening, its strength will increase greatly.

3, good corrosion resistance. One of the characteristics of aluminum alloy is that the surface will form a layer of dense oxide film when it comes into contact with air, which can prevent corrosion, so the corrosion resistance is good. If the "alumina film treatment method" is applied to it, corrosion can be completely prevented.

4, good processing performance. Railway vehicle profile extrusion performance is good, secondary machining, bending processing is easy.

5, easy to regenerate. Aluminum has a low melting point (660 ℃) and easy regeneration. In the disposal of waste is also pollution-free, conducive to environmental protection, in line with the sustainable development strategy.
