Abstract
An iron type golf club head with improved performance is disclosed herein. More specifically, the present invention discloses an iron type golf club head having a frontal face portion made out of a lightweight material that is separate and distinct from the material used to form the remaining body portion of the iron type golf club head. The thinner material allows the frontal face portion of the iron type golf club head to be made thinner, yielding improved performance characteristics such as a higher Coefficient of Restitution (COR) of greater than about 0.770, a lower Center of Gravity (CG) location of less than about 5.0 mm from a ground, and a lower primary resonant frequency of less than about 5,000 Hertz.
