Abstract
A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a striking face that forms a pocket, wherein the pocket is filled with a secondary material having a lower density to improve the performance of the golf club head. The multi-material face disclosed in accordance with the present invention may generally have a characteristic time slope of greater than about 5 and less than about 50, wherein the characteristic time slope is determined based on the various data points collected according to the United States Golf Association'"'"'s (USGA'"'"'s) Characteristic Time (CT) test.

12. A golf club head comprising:
-
a body, further comprising a plurality of cutouts, and made out of a first material having a first density of greater than about 4.0 g/cm3, a face insert, further comprising a plurality of locking tabs, and made out of a second material having a second density of less than about 2.7 g/cm3, at least partially disposed at a frontal portion of said body, wherein said face insert has a thickness of greater than about 0.2 mm and less than about 2.0 mm; wherein said second density is less than said first density; and wherein said plurality of locking tabs engages said plurality of cutouts to secure said face insert onto said body; and wherein said golf club head has a first peak frequency to volume ratio of greater than about 7.0 hertz/cc and less than about 15.0 hertz/cc; said first peak to frequency to volume ratio is defined as a first peak frequency of a signal power diagram of the sound of said golf club head as it impacts a golf ball, divided by a volume of said golf club head. - View Dependent Claims (13, 14, 15, 16, 17, 18)
