ABSTRACT:
A method of making flowable tungsten/copper composite powder by milling an aqueous slurry of a mixture of the desired weight ratio of tungsten powder and copper oxide powder and, optionally, a small amount of cobalt powder, spray-drying the slurry to form spherical, flowable agglomerates, and reducing the agglomerates in a hydrogen atmosphere.
