Although aluminum alloy 6082 and 6061 belong to 6 series of alloys (silicon and magnesium alloy), they are still different. The main difference is that 6082 and 6061 have different proportions of silicon and magnesium.
1, aluminum alloy 6061: Si is 0.4-0.8, Mg is 0.8-1.2, Fe is 0.7.
The main alloying elements of 6061 aluminum alloy are magnesium and silicon, and form Mg2Si phase. If contain a certain amount of manganese and chromium, can neutralize the bad effect of iron; Small amounts of copper or zinc are sometimes added to enhance the strength of the alloy without any significant loss of corrosion resistance
There is also a small amount of copper in the conductive material to offset the negative effects of titanium and iron on electrical conductivity
Zirconium or titanium can refine the grain size and control the recrystallization structure. Lead and bismuth can be added to improve machinability. Mg2Si is solidly dissolved in aluminum, which makes the alloy have artificial aging and hardening function. The main alloying elements in 6061 aluminum alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect.
