Copper Alloy Casting

Casting pure copper is extremely difficult since it may result in surface cracking, porosity problems and the formation of internal cavities. The casting characteristics of copper can be improved adding small amount of other metals including beryllium, silicon, nickel, tin, zinc, chromium and silver.

Cast copper alloys are used for a wide variety of application such as bearings, bushings, gears, fittings, valve bodies and miscellaneous components for the chemical processing industry. These alloys are poured into many types of castings such as sand, shell, permanent mould, chemical sand, centrifugal, and die casting.

Copper alloy casting have high wear qualities when subjected to metal-to-metal contact, machinability, thermal and electrical conductivity, appearance, and corrosion resistance.
