PROBLEM TO BE SOLVED: To obtain a material having high density/high strength and finely dispersing aαphase of Co-Cr alloy phase by accommodating Co-Cr-Zr alloy powder in a metal capsule in an appropriate quantity, evacuating/sealing, heating/strongly pressurizing in a compacting die, taking out a compact to cool and removing a metal part coming from a capsule. SOLUTION: It is appropriate to disperse aαphase of a Co-Cr alloy phase in a size of >=10μm. A composition of a Co-Cr-Zr alloy target consists of 20-40% Cr, 3-50% Zr and the balance Co. A heating temp. of a capsule is >=150 deg.C of the melting point. As an example of a used capsule is of a carbon steel of 148 mm outside diameter, 4 mm thickness, 100 mm length. Alloy powder is produced by e.g. a gas atomizer process. The produced target material is free from crack in machining, a desired alloy target material having mechanical strength is obtained.
