6063A aluminum plate is widely used in the frame of building aluminum doors, windows and curtain walls. It is a common type of aluminum plate.

In order to ensure that doors, windows and curtain walls have high wind pressure resistance, assembly performance, corrosion resistance and decoration performance, the requirements for the comprehensive performance of aluminum alloy profiles are far higher than the standards for industrial profiles. Within the composition range of 6063A aluminum plate specified in the national standard GB/T3190, different values ​​of the chemical composition will result in different material characteristics. When the chemical composition has a large range, the performance difference will fluctuate in a large range. , So that the comprehensive performance of the profile will be out of control.
The chemical composition of 6063A aluminum plate has become the most important part of the production of high-quality aluminum alloy construction profiles.
6063A aluminum plate is a medium-strength heat-treatable and strengthened alloy in the AL-Mg-Si series. Mg and Si are the main alloying elements. The main task of optimizing the chemical composition is to determine the percentage of Mg and Si (mass fraction, the same below) .
The corrosion of 6063A aluminum plate caused by silicon can be prevented and controlled. As long as the purchase of raw materials and alloy composition are effectively controlled, the ratio of magnesium to silicon is within the range of 1.3 to 1.7, and the parameters of each process are strictly controlled. Avoid segregation and liberation of silicon, and try to make silicon and magnesium form a beneficial Mg2Si strengthening phase.
