The main alloying elements of 6063 aluminum alloy are magnesium and silicon, which have excellent processing properties, excellent weldability, extrudability and electroplating properties, good corrosion resistance, toughness, easy polishing, coating, and excellent anodizing effects. It is a typical extruded alloy, widely used in building profiles, irrigation pipes, tubes, rods, and profiles for vehicles, benches, furniture, elevators, fences, etc., and 6063 is generally used in building profiles.

The main alloying elements of 6061 aluminum alloy are magnesium and silicon, and the Mg2Si phase is formed. 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 increase the strength of the alloy without significantly reducing its corrosion resistance; there is a small amount of conductive materials In order to offset the adverse effects of titanium and iron on conductivity; zirconium or titanium can refine the grain and control the recrystallization structure; in order to improve the machinability, lead and bismuth can be added. In Mg2Si, the Mg/Si ratio is 1.73. In the heat treatment state, Mg2Si is solid-melted in aluminum, making the alloy have artificial age hardening function. 6061 requires industrial structural parts with certain strength, weldability and high corrosion resistance. 6061 requires a variety of industrial structures with certain strength, weldability and high corrosion resistance, such as pipes, rods, shapes, etc. for the manufacture of trucks, tower buildings, ships, trams, furniture, mechanical parts, precision processing, etc. Sheet.

Generally speaking, 6061 has more alloying elements than 6063, so the material strength is higher.
