Abstract
A golf club head having a cavity back arrangement and a sandwich construction is disclosed. The club head contains a thin strike face, a metal back flange and a light weight insert located between the strike face and the back flange to provide structural support to the strike face. The insert is in contact with at least a portion of the strike face and is made from light weight materials including magnesium and titanium. The club head is constructed to move the center of gravity lower and toward the back of the club head and to increase the moment of inertia. The insert provides the necessary support with adversely affecting either the center of gravity or the moment of inertia.
