ABSTRACT:
A core metal in a molten state, which is to be pulverized, is put in a vessel in coexistence with a covering powder in a solid state consisting of a material which has a higher melting point than said core metal and is difficult to chemically react with said core metal and/or difficult to form a solid solution with said core metal. Then, said molten core metal and said solid covering powder are mixed thoroughly and uniformly by stirring. Then, while continuing said stirring, said molten core metal and said solid covering powder are slowly cooled until the temperature of the former reaches at least its solidus point to pulverize said core metal into a fine powder and to form a composite powder for powder metallurgy having a structure in which many particles of said covering powder adhere to and cover the entire surface of each particle of said fine powder of said core metal.
