Color Coated Aluminium Coil / Sheet
The properties of aluminium alloy are light weight, excellent electrical and thermal conductivity, high corrosion resistant and ductility.
Aluminium alloy is soft and is usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium to increase strength. When aluminium alloy is exposed to air, an anti-oxidation coating is formed instantly to protect products. Aluminium alloy is one of the lightest metals. The application of products ranges from precision technology to daily commodities.
