Abstract
The history of copper powder is traced back to antiquity, and some obsolete production methods are discussed. The three main processes for production of copper powders are described briefly and the characteristics of the resultant powders compared. Methods available to modify certain critical properties of atomized powders are discussed in technical and economic terms. Copper alloys are described in terms of production, powder characterization, and usage: atomization is shown to be the primary production route, but other methods are discussed. An economic study is made to show the relentless substitution of copper powders by cheaper alternatives, but the powder manufacturers can demonstrate success in the development of new markets and applications.
