ABSTRACT:
In construction of a composite golf club head made up of several shell components united together along their mating edges, a face shell component is made of titanium alloy and a rear shell component is made of pure titanium. The titanium alloy well withstands hard impact at shooting balls by a face whereas use of cheep pure titanium allows plastic shaping of the intricate rear shell component even at a low temperature to significantly lower the total production cost of the golf club head.
