Golf club head
First Claim
1. A golf club head comprising:
- a body having a face wall, a crown wall, a sole wall, a heel wall, a rear wall, and a toe wall, wherein the face wall has an approximately rectangular shape and the face wall has a variable thickness;
wherein the golf club head has a volume ranging from 420 cubic centimeters to 470 cubic centimeters and a mass ranging from 190 grams to 250 grams;
wherein the face wall has an aspect ratio greater than 1.8 for a golf club head;
wherein the golf club head has a moment of inertia about the Izz axis through the center of gravity of the golf club head which is greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head which is greater than 3000 grams-centimeters squared;
wherein the golf club head has a coefficient of restitution that ranges from 0.825 to 0.883, and the golf club head has a standard deviation of coefficient of restitution of greater than zero and less than 0.226.

Abstract
A golf club head (42) having a standard deviation of coefficient of restitution of less than 0.226 is disclosed herein. The golf club head (42) also preferably has a delta of the coefficient of restitution between a geometric face center of the face (72) and a location (806) 0.5 inch sole-ward from the face center that is less than 0.065. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.

12. A golf club head comprising:
-
a face component composed of a first material, the face component comprising a striking plate portion and a return portion, the striking plate portion having varying thickness, a substantially rectangular shape and an aspect ratio greater than 1.8; and an aft-body coupled to the return portion of the face component, the aft-body composed of a second material having a density less than that of the first material, the aft-body comprising a crown portion, a sole portion, the sole portion having a bottom section and a ribbon section, the ribbon section being located between the crown portion and the bottom section of the sole portion; wherein the golf club head a mass ranging from 180 grams to 215 grams, a volume ranging from 420 cubic centimeters to 470 cubic centimeters, a moment of inertia, Izz, about the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia, Iyy, about the center of gravity of the golf club head ranging from 2000 grams-centimeters squared to 4000 grams-centimeters squared; wherein the golf club head has a coefficient of restitution ranging from 0.825 to 0.883, and the golf club head has a standard deviation of coefficient of restitution of greater than zero and less than 0.226. - View Dependent Claims (13, 14, 15, 16, 17)
