Abstract
A golf club ball-striking face (6) utilizing a metal with ten times or higher damping capacity compare to the steels presently in use for club faces. The metal has the strength near that of the steels. The preferred metal is of the class of shape memory metals of alloys including: copper, nickel, aluminum, and manganese. The face is an insert plate whose front ball striking surface is narrower than its rear surface and is secured into a cavity formed in the club head, where the plate may be as thin as 0.010 inches or the plate may extend to nearly the entire thickness of the club head.
Claims1
A golf club head comprising:
- a body having an insert which provides the striking surface of the club head and is made of a material which includes a shape memory metal alloy of the type demonstrating a martensitic transformation shape memory effect and having a damping capacity of at least ten times that of stainless steel, the insert comprising a four sided plate, with a striking surface and a back surface, and having two opposing side edges which are beveled such that the insert striking surface is narrower than the corresponding back surface.
