The difference between aluminum alloy 6063 and 6061

Jun. 02, 2020

    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, excellent anodizing effect, It is a typical extruded alloy. It is widely used in construction profiles, irrigation pipes, pipes, rods, and profiles for vehicles, benches, furniture, elevators, fences, etc. 6063 is generally used in construction 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 increase the strength of the alloy without significantly reducing its corrosion resistance. There are still a few Copper 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, you can add lead and bismuth. In Mg2Si, the Mg/Si ratio is 1.73, In the heat-treated state, Mg2Si is solid-melted in aluminum, giving the alloy an artificial age hardening function. 6061 requires industrial structures with certain strength, solderability, and high corrosion resistance. 6061 requires a variety of industrial structures with certain strength, weldability and high corrosion resistance, such as pipes, rods, profiles, etc. Plate.

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