Difference Between Aluminum Alloy 6063 & 6061
6063 aluminum alloy elements are magnesium and silicon, with excellent processing performance, excellent welding ability, extrusion and electroplating, good corrosion resistance, toughness, easy to polish, film wrapping, excellent on anodizing effect, is a typical extruded alloy, widely used in building profiles, irrigation tubes, vehicles, racks, furniture, lifts, Fences and other tubes, rods, profiles, aluminum alloy 6063 generally used for building.
The main alloying elements of 6061 aluminum alloys are magnesium and silicon which form as mg2si. If it contains a certain amount of manganese and chromium, can be the bad effect 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 also a small amount of copper in the conductive material to counteract the adverse effects of titanium and iron on conductivity. zirconium or titanium can refine grain and control recrystallization microstructure. To improve machinability, lead and bismuth can be added. In the Mg2si, the mg/si ratio is 1.73, in the heat treatment condition, the mg2si is fused in the aluminum, so that the alloy has the artificial aging hardening function.6061 require a certain degree of strength, welding ability and corrosion resistance of a variety of industrial structure, such as to manufacture the trucks, tower building, ships, trams, furniture, machinery parts, precision processing, such as tubes, rods, shapes, sheet which all is6061,it contain more alloy elements than 6063.
