Bronze casting are a kind of copper alloy material which are widely used in the machinery manufacturing industry, ship building, automotive and construction industries. The most popular sorts of bronze castings can be classified as Cu-Sn, Cu-Al, Cu-Pb, Cu-Mn castings. Below are the common grade of

The copper alloy with zinc as the main alloying element is usually called brass. Copper-zinc binary alloy called ordinary brass. With more alloy element added to the material based on copper-zinc alloy, it will be called special brass. Brass casting is widely applied in machinery industry, ship building, aerospace, automotive, construction, etc. The main characteristics of brass casting are wear resistance and anti rust features. Normal production methods for brass castings are die casting, centrifugal casting, lost wax casting and sand casting.
