golf club head |
| abstract |
Disclosed herein is a golf club head that includes a body and a face portion coupled to the body. The facial parts have varying thicknesses. The crown portion of the golf club head has an areal weight of less than about 0.35 g/cm 2 over more than about 50% of its entire surface area. The sole portion of the golf club head has an areal weight of less than about 0.35 g/cm 2 over more than about 50% of its entire surface area. The striking face has a central area defined by a 40 mm by 20 mm rectangular area centered on the center of the striking face and elongated in the heel-to-toe direction. In the central area, the maximum thickness of the face part is not more than 5mm and the minimum thickness is not less than 2.4mm. In the central region, the striking face has a characteristic time of no greater than 257 microseconds. In the central region, no less than 25% of the striking face has a coefficient of restitution of at least 0.8. Within the central region, no less than 60% of the striking face has a CT of at least 235 microseconds. Within the central region, no less than 50% of the striking face has a CT of at least 240 microseconds. |
