.Aluminum alloy introduction:
Medium-strength alloy has good plasticity and excellent corrosion resistance. In particular, it has no tendency to stress corrosion cracking, has excellent weldability, corrosion resistance and cold workability, making it a promising alloy with a wide range of applications. It can be anodized or painted with enamel to adapt to building decoration materials. It contains a small amount and therefore has a higher strength, but its quenching sensitivity is also higher. Wind quenching cannot be achieved after extrusion and requires re-solution treatment and quenching aging to obtain higher strength.
Aluminum alloy elements:
The main alloying elements of aluminum alloy are magnesium and silicon and form phases. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance; there is also a small amount of copper in the conductive material. Offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control the recrystallized structure; lead and bismuth can be added to improve machinability. Solid solution in aluminum gives the alloy artificial age hardening properties. The main alloying elements in aluminum alloys are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect.
