Abstract
A golf club head having a multi-material face is disclosed and claimed. The face is formed by explosion welding, allowing materials having substantially different properties to be uniformly joined. Explosion welding allows the materials to be joined together via a cold-working process, allowing them to joined without losing their pre-bonded properties. Thus, the golf club head have a hard, wear resistant material as the ball-impacting face surface explosion welded to a softer material, allowing the multi-material face to be joined to a soft body material such that the body can be bent and customized. The multi-material face also allows for improved playing characteristics by allowing the club designer to use a thinner face and lighter body material while still providing improved face wear resistance and durability.

13. A golf club head, comprising an outer striking face defining grooves therein, wherein the entirety of each groove and area immediately surrounding each groove is formed from a first material having a first wear resistance, and wherein a second material having a second wear resistance forms the portions of the outer striking face between the areas immediately surrounding each groove, wherein the first wear resistance is greater than the second wear resistance;
wherein the grooves travel substantially the length of the outer striking face. - View Dependent Claims (14, 15, 16)
