Golf club made of a bulk-solidifying amorphous metal
First Claim
1. A golf club head made at least in part of a bulk-solidifying amorphous metal that may be cooled from the melt at a cooling rate of about 500°
- C. per second or less, yet retain an amorphous structure, the golf club head being fabricated by casting the bulk-solidifying amorphous metal to shape in a mold.

Abstract
A golf club is made of a club shaft and a club head. Either the club shaft or the club head is made at least in part of a bulk-solidifying amorphous metal. A preferred bulk-solidifying amorphous metal has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 38 percent total of copper plus nickel, plus incidental impurities, the total of the percentages being 100 atomic percent. The weights of the various club heads of a set, which have different volumes, may be established by varying the compositions and thence the densities of the bulk-solidifying amorphous alloys.
