The main alloy elements of 6063 aluminum alloy are magnesium and silicon, with excellent processing performance, excellent weldability, extrudability, and electroplating, good corrosion resistance, toughness, easy polishing, coating, and anodic oxidation effect are excellent, is a typical extrusion alloy, widely used in building profiles, irrigation pipes, for vehicles, benches, furniture, lifts, fences, and other tubes, rods, Profile 6063 is commonly used for building profiles.

The main alloying elements of 6061 aluminum alloy are magnesium and silicon which form the Mg2Si phase. 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 also a small amount of copper in the conductive material to offset the bad effects of titanium and iron on the conductivity; Zirconium or titanium can refine grains and control recrystallization structure; Lead and bismuth can be added to improve machinability. In Mg2Si, the Mg/Si ratio is 1.73. In the heat treatment state, Mg2Si is fused into aluminum, so that the alloy has the function of artificial aging hardening. Industrial structural parts with a certain strength, weldability, and high corrosion resistance are required. 6061 requires a certain strength, weldability, and high corrosion resistance of various industrial structures, such as the manufacturing of trucks, tower buildings, ships, trams, furniture, machine parts, and precision machining of the pipe, rod, shape, and plate.

In general, 6061 has more alloying elements than 6063, so the material strength is higher.
