Abstract
A hitting face of a golf club head having improved flexural stiffness properties. In one embodiment, the hitting face is made from multiple materials. Each material has a different tensile modulus of elasticity, where the center of the hitting face has a much higher tensile modulus of elasticity than the surrounding portions of the hitting face. This creates a stiff center and a more easily deflected concentric portion. In another embodiment, the materials have different yield strengths, where the center of the hitting face has a very high yield strength compared to the surrounding portions of the hitting face. The hitting face may then plastically deform around its periphery, while the center retains its original shape.
