Aluminum alloy lightweight advantages and more ideal structure materials are not selected

[China Aluminum Industry Network] Aluminum is a face-centered cubic structure, so it has high plasticity, easy processing, can be made into a variety of profiles, plates, corrosion resistance is good; but the strength of pure aluminum is very low, it is not suitable for structural materials . Through long-term production practices and scientific experiments, people have gradually strengthened aluminum by adding alloying elements and using heat treatment methods. This has led to a series of aluminum alloys. Aluminum-based alloys are alloys. The alloy formed by adding a certain element has high strength while maintaining the advantages of pure aluminum light, and it is close to or more than high-quality steel, good plasticity, can be processed into various profiles, has excellent conductivity, thermal conductivity and resistance Eroded. Become an ideal structural material, widely used in machinery manufacturing, transportation machinery, power machinery and aerospace industries, aircraft fuselage, skin, compressor, etc. often made of aluminum alloy, in order to reduce their own weight. The use of aluminum alloy instead of steel plate welding can reduce the structural weight by more than 50%.
