6061 is a heat-treatable reinforced alloy with good formability and machinability, as well as medium strength, which can maintain good operability after annealing.
The main alloying elements of 6061 alloy are magnesium and silicon, and form the Mg2Si 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 still a small amount of conductive material. copper to offset the influence of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control recrystallization structure; for machinability, lead and bismuth can be added. Mg2Si is solid-dissolved in aluminum, which makes the alloy have artificial aging hardening function.
- 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 2XXX series or 7XXX series, its magnesium and silicon alloys have many characteristics and have processability. , Excellent characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material and easy to polish, easy to color film, oxidation effect and other excellent characteristics.
