Abstract
A weight member for a golf club head is made of a WMoNi alloy by powder metallurgy or a precision casting process. The WMoNi alloy includes tungsten 1-35 wt %, molybdenum 4-55 wt %, and nickel 25-95 wt %, and has a specific gravity ranging between 8.6 and 13.3. Molybdenum increases the density of the weight member and improves the rust-resisting property of the weight member. The tungsten, molybdenum, and nickel provide a uniform metallographic phase. Uniformity of polishing of the weight member is thus improved.
