Aluminium Bronze Casting are required in many industries. This type of casting has successfully replaced iron casting as it reduces component’s weight by half. Various auto producers are looking for fields where they may replace iron parts with aluminum parts. Some of the vital features comprises lightweight, good corrosion resistance, retains strength at high temperatures, high dimensional stability, high electrical and thermal conductivity, etc. Many Aluminum Casting Manufacturers, Suppliers, and Exporters are engaged in offering high quality Aluminum Castings.
Gunmetal can also mean steel treated to simulate gunmetal bronze. Bushings made of this metal are used in machinery.
