Abstract
Golf club heads comprising weighted materials that can be added, removed, and moved in order to change the weight and center of gravity of the club. In some instances, the weighted material is a polymer composition comprising metal and having a specific gravity greater than about 4. Also disclosed are methods of modifying the center of gravity of a golf club head and methods of manufacturing golf club heads.
Claims5
A method of modifying the center of gravity of a golf club head comprising:
- removing a portion of a club head, having a face, a back, a heel, a toe, a sole, and a crown that together form a hollow interior volume, to access the interior of the club head;
- contacting the interior of the club head with a polymer composition comprising a metal and having a specific gravity greater than about 4;
- and
- reassembling the club head.
