The main alloying elements of 6063 aluminum alloy are magnesium and silicon, which has excellent processing performance, excellent weldability, extrudability and electroplating, good corrosion resistance, toughness, easy polishing, upper coating, excellent anodizing effect, It is a typical extrusion alloy, widely used in building profiles, irrigation pipes, pipes, rods, profiles for vehicles, benches, furniture, lifts, fences, etc. 6063 is generally used for building profiles.
The main alloying elements of 6061 aluminum 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 also a small amount of conductive material. copper to offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control recrystallization; in order to improve machinability, lead and bismuth can be added. In Mg2Si, the ratio of Mg/Si is 1.73. In the heat treatment state, Mg2Si is solidified in aluminum, which makes the alloy have artificial aging hardening function.
6061 requires industrial structural parts with certain strength, weldability and high corrosion resistance. 6061 requires various industrial structures with certain strength, high weldability and high corrosion resistance, such as pipes, rods, shaped materials, plate.
Generally speaking, 6061 has more alloying elements than 6063, so the material strength is higher.
