The main alloying elements of 063 aluminum alloy are magnesium and silicon. It has excellent workability, outstanding weldability, extrudability, and plating properties, good corrosion resistance, toughness, is easy to polish, apply a top coating, and has excellent anodizing effects. It is a typical extrusion alloy, widely used for building profiles, irrigation pipes, vehicle supplies, benches, furniture, lifts, fences, and other pipes, rods, and profiles. 6063 is generally used for building profiles.
The main alloying elements of 6061 aluminum alloy are magnesium and silicon, forming the Mg2Si phase. If a certain amount of manganese and chromium is present, they can counteract the adverse effects of iron; sometimes a small amount of copper or zinc is also added to increase the strength of the alloy without significantly reducing its corrosion resistance. In conductive materials, a small amount of copper is added to offset the negative impact of titanium and iron on conductivity. Zirconium or titanium can refine the grain and control the recrystallized structure. To improve machinability, lead and bismuth can be added. In Mg2Si, the Mg/Si ratio is 1.73. In the heat-treated state, Mg2Si dissolves in aluminum, giving the alloy artificial aging hardening properties. 6061 requires certain strength, weldability, and high corrosion resistance for industrial structural components. 6061 requires various industrial structural elements with certain strength, weldability, and high corrosion resistance, such as pipes, rods, profiles, and plates used for manufacturing trucks, tower constructions, ships, trams, furniture, machinery parts, and precision machining.
Overall, 6061 has a higher content of alloying elements than 6063, so the material strength is higher.
