GOLF CLUB USING CU-ZN-SN-BASE VIBRATION DAMPING ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a golf club which is a golf club absorbing impact in hitting and having an excellent hitting feel and has good workability and recyclability. SOLUTION: This golf club head is constituted by using a Cu-Zn-Sn-base vibration damping alloy which is a Cu-Zn-Sn-base having aβphase permitting martensite transformation and having vibration damping characteristics by accompanying the transformation twinning of thisβphase and has an Sn content of 0.5 to 20 wt.% in at least a portion of a head of the golf club head. Aγphase is deposited in a portion of the head, by which the strength is improved as well.
