Abstract

A golf club head (20) having a body (22) with a front wall (30) with an opening (32) and a striking plate insert (40) is disclosed herein. The golf club head (20) has a volume between 370 cubic centimeters and 425 cubic centimeters. The golf club head (20) has a mass between 140 grams and 215 grams. The golf club head (20) has a moment of inertia, Izz, about the Z axis through the center of gravity of the golf club head ranging from 3200 g-cm² to 3900 g-cm².

Claims

1. A golf club head comprising:

a body having a crown, a sole, a ribbon, and a front wall with an opening, the crown having a thickness of 0.035 inch to 0.045 inch, the sole having a thickness of 0.035 inch to 0.045 inch, the body composed of a cast titanium alloy material, the crown, the sole, the ribbon and the front wall defining a hollow interior; and

a striking plate insert positioned within the opening and welded to the body, the striking plate insert having a uniform thickness in the range of 0.080 inch to 0.120 inch, the striking plate insert composed of a formed titanium alloy material;

an internal hosel positioned within the hollow interior of the body, the interior hosel extending from the crown to the sole;

wherein the golf club head has a volume ranging from 360 cubic centimeters to 425 cubic centimeters;

wherein the golf club head has a mass ranging from 185 grams to 215 grams;

wherein the golf club head has a height ranging from 2.0 inches to 3.5 inches and a width ranging from 4.0 inches to 5.0 inches;

wherein the golf club head has a coefficient of restitution ranging from 0.82 to 0.87; and

wherein the golf club head has a moment of inertia, Izz, about the Z axis through the center of gravity of the golf club head ranging from 3400 g-cm² to 3900 g-cm².

2. A golf club head comprising:
