Abstract
A ball striking device, such as a golf club head, includes a face having a ball striking surface, an inner surface opposite the ball striking surface, and a thickness defined between the ball striking surface and the inner surface, and a body connected to the face and extending rearward from the face. The face has a modulus gradient across the thickness of the face, such that the modulus of the face varies at different distances from the ball striking surface. The face may also include at least one of an insert, a composite material, a multi-layered structure, and/or a portion treated by a surface treatment to contribute to the modulus gradient.
