6061 is a heat-treatable strengthenable alloy with good formability, weldability, and machinability. It also has medium strength and can maintain good operability after annealing. The main alloying elements of nt6061 alloy are magnesium and silicon. , and form 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 are also a small amount of conductive materials. Copper is used to offset the adverse effects of iron and iron on conductivity, or iron can refine grains and control the recrystallized structure; in order to improve machinability, lead and iron can be added. Mg2Si is solid dissolved in aluminum, giving the alloy artificial age hardening properties.

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 2XXX series or 7XXX series, it has many magnesium and silicon alloy properties and has processability Excellent, excellent welding characteristics and plating properties, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, easy coloring film, excellent oxidation effect and other excellent features.
