Abstract
A face wall for the hitting face of a golf club head is supported on a hollow structural shell. The face wall is formed to realize maximum face strength with minimum face mass. This is accomplished by varying the thickness of the face wall so it is thickest in the general vicinity of the face center and becomes thinner toward the edges of the face. This allows the club head to weigh less, incorporate a large face area and adequate strength while maintaining high moments of inertia of the head.
