摘要
The present invention provides a tungsten skeleton structure and a tungsten-copper composite material including the skeleton structure by eliminating non-uniform shrinkage of the molded body which may occur during liquid phase sintering and by simply injection molding only tungsten powder at low cost. 2 to 5 μm and 99.9 by weight percent Tungsten powder surface with purity over 0.06 (600 ppm) by weight Coating with less than Ni to form a raw powder; Mixing the raw material powder with a polymer binder to produce a feedstock for injection; Powder injection molding the feedstock; A method of producing a tungsten skeleton structure and a method of producing a tungsten-copper composite material using the tungsten skeleton structure are provided.
