Method of manufacturing a composition for use in injection molding powder metallurgy

摘要

A composition for use in injection molding powder metallurgy, is provided by applying mechanical sphericalization to a metal powder of an irregular shape and having an average grain size of not more than 50 mu m to form a sphericalized metal powder, and then mixing and kneading a binder of not more than 9 parts by volume relative to 11 parts by volume of the sphericalized metal powder.
