Aluminum alloy elements
The main alloying elements of aluminum alloy are magnesium and silicon and form a phase. 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 to offset it. The adverse effects of titanium and iron on electrical conductivity. Zirconium or titanium can refine the grains and control the recrystallized structure. In order to improve the machinability, lead and bismuth can be added. 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.
