Aluminum alloys (JIS H4000) are alloys in which aluminium (Al) is the predominant metal.
The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc. About 85% of aluminum is used for wrought products, for example rolled plate, foils and extrusions. Aluminum alloys has excellent processability, high electrical conductivity and corrosion resistance while yield cost-effective products due to the low melting point, they are now widely used in engineering structures and components where light weight or corrosion resistance is required.
The weight is lighter than other high-strength materials (specific gravity 2.7 is 1/3 of iron). Suitable for circuits in airplanes, construction materials, aluminum cans, and electronic equipment Various products such as radiating plates. In addition, because aluminum is highly reusable, it can save energy and is an environmentally friendly material.
Moreover, Various colors can be carried out on Aluminum alloy through an automatic coating production line. The coating after the molding process can save surface treatment, improve protection, and exert various additional functions. It is a functional, creative, and economical colored aluminum material that can be used in a wide range of fields.
In general, Aluminum alloy is given a four-digit number, where the first digit indicates the major alloying elements. Common series include:
