Powder Coating Extrusion Aluminum Profile 6063 for Windows and Prefabricated Houses

4 series aluminum alloy based on silicon as the main alloying element of aluminium alloy, its most alloys are not reinforced aluminum alloy heat treatment, only including Cu, and Ni alloy, Mg and learned some after welding heat treatment strengthening alloy elements, can only through strengthening heat treatment. Department alloys due to their high silicon content, low melting point, good melt flow, easy feeding, brittleness, and not of the final product so adding material mainly used in the manufacture of aluminum alloy welding, such as soldering plate, wire electrode and candle. In addition, due to some of the piston and heat resistant parts. The alloys containing about 5% of silicon are black and gray after anodizing, so they are suitable for building materials and decorative parts.
