Main alloy elements for magnesium silicon, 6063 aluminum alloy has the excellent processing performance, excellent weldability, extrusion electroplating, good corrosion resistance, toughness, easy to polish, coated, anodized effect is good, is a typical extrusion alloy, widely used in building material, irrigation pipe, for vehicles, bench, furniture, elevators, fence etc with tube, rod, profiles 6063 commonly used in building material.
The main alloying elements of 6061 aluminum alloy are magnesium silicon, which form Mg2Si phase. If contain certain amount of manganese chromium, can neutralize the bad effect of iron; Sometimes a small amount of copper zinc is added to enhance 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 iron on the conductivity; Zirconium titanium can refine grain control recrystallization structure. In order to improve the machinability, lead bismuth can be added. In Mg2Si, the Mg/Si ratio is 1.73. In the state of heat treatment, Mg2Si is solidified in aluminum, so that the alloy has the function of artificial aging hardening. 6061 requires industrial structures with certain strength, weldability high corrosion resistance. 6061 requires various industrial structures with certain strength, weldability high corrosion resistance, such as pipes, rods, shapes plates used in the manufacture of trucks, tower buildings, ships, trolleys, furniture, machine parts precision machining.
In general, the alloy element content of 6061 is more than that of 6063, so the material strength is higher.
