Patent Images
1. A golf club comprising:
- a body with a striking plate, a heel end, a toe and a cavity; and
a weighting member formed in the cavity of the body, the weighting member composed of a pressed multiple component powder material consisting essentially of tungsten in an amount of 50 to 95% volume of the multiple component powder material and tin in an amount of 5 to 50% volume of the multiple component powder material, wherein the weighting member has a density ranging from 15.5 g/cm3 to 16.7 g/cm3, wherein the weighting member has a density that is 80% to 90% of the theoretical density of the multiple component powder material, wherein the weighting member has a porosity that is less than 10% of the volume of the weighting member.

7. An iron-type golf club head comprising:
-
a body having a striking plate, a toe end, a heel end, a main rear cavity opposite the striking plates the main rear cavity defined by a top wall, a bottom wall, a heel wall and a toe wall, the bottom wall having a second cavity with a predetermined configuration, and a weighting member formed within the second cavity and occupying the entire cavity, the weighting member composed of a pressed multiple component powder material consisting essentially of tungsten in an amount of 80%-90% volume of the multiple component powder material and tin in an amount of 10%-20% volume of the multiple component powder material, where the weighting member has a density ranging from 15.5 g/cm3 to 16.7 g/cm3, wherein the weighting member has a density that is 80% to 99% of the theoretical density of the multiple component powder material, wherein the weighting member has a porosity that is less than 10% of the volume of the weighting member. - View Dependent Claims (8, 9)
