1. A method of producing a golf club head with a specific weight, the golf club head having an internal cavity defined by a plurality of walls of the golf club head, the internal cavity having an opening for access thereto, the method comprising:
- placing a plurality of tungsten spheres within the internal cavity;
dispensing a second weight material into the internal cavity, the second weight material heated to a liquid phase, the second weight material having a density that is lower than tungsten;
imparting vibrational energy to orient the plurality of tungsten spheres throughout the second weight material within the internal cavity; and
cooling the second weight material to a solid phase within the internal cavity.

9. A method of producing a golf club head with a specific weight, the golf club head having an internal cavity defined by a plurality of walls of the golf club head and having an opening for access thereto, the method comprising:
-
placing a first weight material into the internal cavity through the opening, the first weight material having a density ranging from 12 g/cm3 to 20 g/cm3;
dispensing a second weight material into the internal cavity through the opening, the second weight material heated to a liquid phase, the second weight material having a density that is less than the density of the first weight material;
imparting vibrational energy to the golf club head to provide intimate contact between the first weight material which forms a discontinuous phase and the second weight material which forms a continuous phase; and
cooling the second weight material to a solid phase within the internal cavity. - View Dependent Claims (10, 11, 12)

13. A method of producing a golf club head with a specific weight, the golf club head having an internal cavity defined by a plurality of walls of the golf club head, the internal cavity having an opening for access thereto, the method comprising:
-
placing a plurality of tungsten alloy spheres within the internal cavity;
dispensing a bismuth-tin solder into the internal cavity, the bismuth-tin solder heated to a liquid phase;
imparting vibrational energy to orient the plurality of tungsten alloy spheres throughout the bismuth-tin solder within the internal cavity; and
cooling the bismuth-tin solder to a solid phase within the internal cavity.- View Dependent Claims (14, 15, 16)
