Painted Color Aluminum Alloy Sheet Plate For Construction Materials
Aluminum Manufacturer Painted Color Aluminum Sheet/Plate For Construction Materials
4000 series aluminum alloys (Al-Si series alloys) are aluminum alloys with silicon as the main alloying element (silicon content is between 4.5-6). Due to the high silicon content, low melting point, good melt fluidity, easy feeding and no brittleness of the final product, this series of alloys is mainly used for the manufacture of additive materials for aluminum alloy welding, such as brazing plates, electrodes and welding wire, etc. In addition, due to the good wear resistance and high temperature performance of some alloys of this series, they are also used to manufacture automobile pistons and heat-resistant parts. The alloy containing about 5% silicon is black-gray after anodizing and coloring, so it is suitable for building materials and manufacturing decorative parts.
