Ordinary duralumin alloy, good machinability, medium strength

6061 is a kind of heat-treatment strengthening alloy, which has good formability, weldability, machinability and medium strength. It can still maintain good operability after annealing

The main alloy elements of 6061 alloy are magnesium and silicon, and Mg2Si phase is formed. If it contains a certain amount of manganese and chromium, 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 a small amount of copper in the conductive material to offset the adverse effect of titanium and iron on the conductivity; zirconium or titanium can refine the grain and control the recrystallization structure; in order to improve the machinability, lead and zinc can be added Bismuth. When Mg2Si is dissolved in aluminum, the alloy has the function of artificial age hardening.

6061-T651 is the main alloy of 6061 alloy. It is a high-quality aluminum alloy product produced by heat treatment and pre stretching process. Although its strength cannot be compared with that of 2XXX system or 7xxx system, it has many magnesium and silicon alloy characteristics, excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness, no deformation after processing, compact and defect free materials, and easy to polish and polish The color film is easy and the oxidation effect is excellent.
