Powder Metallurgy Copper and Copper Alloys
Selection of the process steps used, powder chosen, and lubricant choice have marked effects on the quality of a sintered component. This article describes the alloy composition, mechanical and structural properties, processing routes, and advantages of the common members of the copper alloy family, namely, pure copper, brass, and bronze, which all aid in the selection of the suitable material for structural and bearing applications. It outlines the structural applications of nickel silver alloys.
This article describes the fundamentals of various techniques used for the production of copper and copper alloy powders. These include atomization (water, air, and gas), oxide reduction, and electrolysis. The article discusses the effects of electrolyte composition and operating conditions on the characteristics of copper and copper alloy powders.
