Aluminium Disc

The advantages of aluminium alloy are lightweight, excellent electrical and thermal conductivity, high corrosion resistance and ductility.

Aluminium alloy is soft and usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium to increase strength. When aluminium alloy is exposed to air, an anti-oxidant coating will be formed instantly to protect products. Aluminium alloy is one of the lightest metals. The application of products ranges from precision technology to daily commodities.
