Weight member for a golf club head
First Claim
1. A weight member for a golf club head, the weight member being made by a WMoNi alloy in a precision casting process, the WMoNi alloy comprising a composition of molybdenum 4-55 wt %, nickel 25-95 wt %, and tungsten 1-70 wt %, wherein said weight member comprises of a WMoNi-alloy casting, and the composition of said molybdenum, nickel and tungsten provide a uniform metallographic phase that prevents a surface of the WMoNi-alloy casting from precipitation of tungsten in the precision casting process.

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 1-70 wt %, molybdenum 4-55 wt %, and nickel 25-95 wt %. 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 shining finishing of the weight member is thus improved.
