Abstract
The invention provides a golf club head that uses a light-weight material for part of the body and a strong material for a face-to-sole transition to provide a durable face with a high coefficient of restitution. The club head may have a first body part and a second body part. Material of the first body part extends down from a face member, bends around a face-sole transition, and continues into a sole return member to provide at least a portion of a ball-striking face and a sole surface. The first body part also provides a hosel. The second body part provides a significant proportion of the volume of the club head (e.g., at least about a third or even a majority). The low-density of the second body part allows for inclusion of one or more high-density third body parts to optimize mass distribution.
