Within the composition range of 6063 aluminum alloy tube specified in national standard GB/T3190, different values of chemical composition will result in different material characteristics. When the range of chemical composition is large, its performance difference will fluctuate in a large range, so that the comprehensive performance of the profile can't be controlled.
The chemical composition of 6063 aluminum alloy has become the most important link in the production of high quality aluminum alloy building profiles.6063 aluminum alloy is a heat-treatable alloy with moderate strength in al-Mg-SI system. Mg and Si are the main alloy elements. The main job of optimizing chemical composition is to determine the percentage of Mg and Si (mass fraction, the same below).The effect of Mg and The influence of Mg and Si composition of the strengthening phase Mg2Si, the higher the content of Mg, the more the number of Mg2Si, the greater the heat treatment strengthening effect, the higher the tensile strength of the profile, but the deformation resistance will also increase, the plastic decline of the alloy, the processing performance deteriorated, corrosion resistance deteriorated.The role of Si and the amount of Si influencing Si shall enable all Mg in the alloy to exist in the form of Mg2Si phase to ensure that the role of Mg is fully played.With the increase of Si content, the grain size of the alloy becomes thinner, the metal fluidity increases, the casting performance becomes better, the heat treatment intensification effect increases, the tensile strength of the profile increases while the plasticity decreases, and the corrosion resistance becomes worse.
6063 sandblasting anodized aluminum tube pipe is widely used in electric heating materials, air conditioning refrigeration, petrochemical, mechanical equipment, outdoor appliances, household sanitary ware, electronic appliances accessories, household and commercial drinking water pipes and other industries by customers great praise.
