The golf club head made of 6A1-4V-Ti titanium alloy has relatively high elasticity, zero strength, the same strength and lower density than the earlier club head made of stainless steel.

In addition, the elastic deformation force higher than that of stainless steel can provide a large elastic deformation ability when hitting the ball, and can also generate a large degree of elastic deformation-elongation, and can relatively reduce the golf ball when hitting the impact panel. The resulting ball is compressed and deformed to reduce the degree of damping of the ball striking stress, avoid the energy loss of the ball striking stress, and further increase the hitting distance. 5 200932920 However, under the customary requirements of large and diversified golf club heads, there is a need to develop low mechanical strength to improve design margin. [Invention] In view of the above needs, the problem to be solved by the present invention is to provide a reworked It (five) ductility titanium|3 alloy for adjusting the elastic I of the golf club head.
