Abstract
A composite material golf club head is provided having a body made from a first metal and a face insert press fitted to a portion of the body and made from a second metal. The metals are chosen so that the first metal is heavier than the second metal. The second metal is disposed towards the front and top of the body, and is preferably hard-anodized. In addition, an interlocking structure, for example rectangular or dove tail shaped channels, is provided in the body so that the face insert becomes embedded in the interlocking structure to anchor the face insert to the body. Portions of the golf club head, such as the face insert or sole plate, are anodized to protect against corrosion. The anodized coating is colored to improve aesthetic characteristics or infused with a polymer to increase or reduce friction.
