The present work illustrates the use of water-soluble cupric salts as ingredients of binder for injection molding of Cu. Parts produced are dense, homogeneous and have good surface finish, compared to those produced using conventional binder system. This new binder system provides also process-simplification benefit. with the purity of was selected for this study. Rapid sintering process involving thermal decomposing was successful in densification for 1h. Final density that is about of theoretical value could be obtained, and are distinguishable from conventionally processed W-Cu composites.
