Golf club head |
| abstract |
Disclosed herein is a golf club head that comprises a body and a face portion coupled to the body. The face portion has a thickness that varies. An areal weight of the crown portion of the golf club head is less than about 0.35 g/cm 2 over more than about 50% of an entire surface area of the crown portion. An areal weight of the sole portion of the golf club head is less than about 0.35 g/cm 2 over more than about 50% of an entire surface area of the sole portion. The strike face has a central region, defined by a forty millimeter by twenty millimeter rectangular area centered on a center of the strike face nand elongated in a heel-to-toe direction. Within the central region, a maximum thickness of the face portion is no more than 5 mm and a minimum thickness of the face portion is no less than 2.4 mm. Within the central region, the strike face has a characteristic time (CT) of no more than 257 microseconds. Within the central region, no less than 25% of the strike face has a coefficient of restitution (COR) of at least 0.8. Within the central region, no less than 60% of the strike face has a CT of at least 235 microseconds. Within the central region, no less than 50% of the strike face has a CT of at least 240 microseconds. |
