Golf club head

Abstract

A golf club head showing good ball bouncing performance is provided with good cold workability and age hardenability. The golf club head is characterized in that at least the face thereof is made of a titanium alloy consisting of, by mass %, V: 15 to 25%, Al: 2.5 to 5%, and one or both of Sn: 0.25 to 2.0% and Zr: 0.5 to 4.0%, with the balance being Ti and impurities. The content of hydrogen among the impurities is desirably 0.05% or less. The golf club head of the present invention can have a face thickness of 1 to 3.0 mm, a head volume of 200 to 500 cm 3 , and a head weight of 170 to 220 g.
