The performance advantages of aluminum alloys

Feb 14 , 2022
1. Light and soft. The density of aluminum is 2171g/cm3, which is about one-third of the density of steel; the 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. However, after heat treatment strengthening and alloying strengthening, its strength will be greatly increased.

3. Good corrosion resistance. One of the characteristics of aluminum alloys is that when exposed to air, a dense oxide film will be formed on the surface, which can prevent corrosion, so it has good corrosion resistance. If the "aluminum oxide film treatment method is applied to it, the corrosion can be completely prevented.

4. Good processing performance. The extrusion performance of the profiles for railway vehicles is good, and the secondary machining and bending are also easier.

5. Easy to regenerate. Aluminum has a low melting point (660 ℃) and is easy to regenerate. It is also pollution-free when disposing of it, which is beneficial to environmental protection and conforms to the sustainable development strategy.
