6063 aluminium sheet is a medium-strength heat-resistant strengthened alloy in the AL-Mg-Si series. Mg and Si are the main alloying elements. The percentages of Mg and Si are different, and the characteristics are also different. The higher the Mg content, the greater the amount of Mg2Si, and the greater the heat treatment strengthening effect; increasing the Si content, the alloy grains become finer, the metal fluidity increases, the casting performance becomes better, and the heat treatment strengthening effect increases. The aluminium 6063 has generally good mechanical properties and is heat treatable and highly weldable. The material can be re-heat-treated to restore a higher temper for the whole piece. However, it has half the strength of aluminum 6061 alloys. It is typically produced with very smooth surfaces fit for anodizing.
