A method for manufacturing a golf club head having a weighting member, the method comprising:
- providing a golf club head with a cavity;
- introducing a multiple component material having a high density component, a binding component and an anti-oxidizing component into the cavity of the golf club head;
- wherein the high density component comprises from 5 to 95 weight percent of the weighting member, the binding component comprises from 4 to 49 weight percent of the weighting member and the anti-oxidizing component comprises from 0.5 to 30 weight percent of the weighting member;
- and
- heating the golf club head to allow the multiple component material to the liquid phase temperature for liquid phase sintering of at least one component of the multiple component material.
