ABSTRACT:
Disclosed is a powder metallurgical mixed powder capable of preventing the defective dispersion, that is, the segregation of physical property improving powders and a lubricant powder without reduction in lubricity, and of suppressing the generation of dust upon handling of powders; and a powder metallurgical binder capable of realizing such a mixed powder. The binder including a copolymer containing monomer components of ethylene and propylene, which may be combined with a liquid binder having a specified composition as needed, is added to a powder metallurgical raw powder.
