Abstract

Cast copper alloys are used for their generally superior corrosion resistance, high electrical and thermal conductivities, and good bearing and wear qualities. These alloys are identified by Unified Numbering System designation. Irregular and complex external and internal shapes can be produced by various casting methods at less overall cost than by other means. The commonly used casting methods are compared, and casting characteristics of both single and polyphase alloys are described.

Cast copper alloys include both yellow and red brasses as well as semired brasses and many bronzes. Alloy composition, on which the alloy properties depend, and usage are given.
