The primary alloying element of the 6061 alloy is magnesium and silicon, and constitutes the Mg2Si phase. If a certain amount of manganese and chromium are enriched, it can neutralize the bad effect 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 to offset the adverse effects of titanium and iron on conductivity; zirconium or titanium can refine grains and manipulate recrystallization arrangements; in order to improve the machinability, lead and lead. The Mg2Si is dissolved in aluminum to give the alloy an artificial age hardening function.
6061 aluminum plate chemical composition:
Aluminum Al : balance silicon Si : 0.40 ~ 0.8 copper Cu : 0.15 ~ 0.4 magnesium Mg: 0.80 ~ 1.2 zinc Zn: 0.25
Manganese Mn: 0.15 Ti Ti: 0.15 Fe Fe : 0.7 Chromium Cr: 0.04 to 0.35 Single: 0.05
6061 aluminum plate is an Al-Mg-Si alloy with medium strength, excellent plasticity and excellent corrosion resistance. In particular, it has no stress corrosion cracking tendency, excellent weldability, good corrosion resistance and cold workability, and is an alloy with a wide range of uses. It can be anodized or painted, or it can be painted with enamel. It is rich in a small amount of Cu, so the strength is higher than 6063, but the quenching sensitivity is also higher than 6063. After kneading, wind quenching cannot be achieved. The demand for solid solution treatment and quenching aging is required to obtain higher strength.
