US 2013/0281231 A1 · IRON GOLF CLUB HEAD WITH IMPROVED PERFORMANCE

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.

Dependent claims

An iron type golf club head comprising:

a frontal face portion, made out of a first material having a first density, connected to a forward portion of said iron type golf club head;
a body portion, made out of a second material having a second density, connected to a rear portion of said frontal face portion providing a structural support for said frontal face portion;
wherein said first material is different from said second material;
wherein said first density is lower than said second density;
and
wherein said iron type golf club head has a face replacement ratio of greater than about 0.9 and less than about 1.0;
said face replacement ratio is calculated by dividing a cross-sectional height of said frontal face portion by a total cross-sectional height of a striking surface of said iron type golf club head.
