Brass sang casting and copper alloy is an important kind of nonferrous metal, widely used in the actual production. Commonly used in accordance with the composition of copper alloy is divided into two main categories, namely, casting and casting of bronze. Both sand casting or investment casting, smelting are casting production is very important a ring, all kinds of copper alloy smelting have similarities, and differences, in the years of production practice, we summarize the pure copper and copper alloy is mainly bronze and brass smelting process experience.
Copper based alloys with zinc as the main alloying element are brass, which is divided into two types, which are ordinary brass and special brass. Two ordinary brass is an alloy composed of copper and zinc, mainly used for pressure processing. Based on the other with ordinary brass alloy elements such as silicon, aluminum, manganese, lead, iron and nickel, become special brass. Cast brass are mostly special brass.
