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. Disclosed herein is a golf club head having a body portion and a face insert. The front of the body portion further comprises a cutout sized and dimensioned to receive the face insert.

Abstract: A golf club head having a low-density interchangeable insert located in a top portion thereof.

Abstract: A golf club head formed of multiple materials is disclosed. Those portions of the club head that are subject to high stresses during normal use of the golf club head are formed of a metallic material. Most of the material beyond what is required to maintain structural integrity, however, is removed and replaced with a lightweight material. This freed-up mass that can be redistributed to other, more beneficial locations of the club head. The lightweight material also damps vibrations generated during use of the golf club. This vibration damper may be retained in a state of compression to enhance the vibration damping. One or more weight members may be included to obtain desired center of gravity position, moments of inertia, and other club head attributes.

Abstract: An improved golf club head is disclosed which comprises the positioning of secondary weights at such low, rearward and outward locations that it causes an alteration in the traditional look of the club head wherein each secondary weight has a portion of the weight that bulges outwards of the natural contour of the club head.
