Abstract
Embodiments of golf club heads and methods to manufacture such a golf club heads are generally described herein. In some embodiments, the golf club head may include a ball-striking face and a protective aluminum oxide layer coupled to the ball-striking face of the golf club head. The protective aluminum oxide layer is associated with a hardness that is greater than that of the ball-striking face. In further embodiments, golf club heads may include a top portion and at least one of a plurality of interchangeable alignment indicia coupled thereto, which are configured to guide the golf club head relative to a golf ball.
Claims7
A golf club head comprising:
- a ball-striking face, wherein the ball-striking face is associated with a first hardness;
- and
- a protective aluminum oxide layer coupled to the ball-striking face,
- wherein the protective aluminum oxide layer is associated with a second hardness, and wherein the second hardness is greater than the first hardness;
- the ball-striking face comprises, by weight, about 0.8% to about 1.2% magnesium, about 0.4% to about 0.8% silicon, about 0.15% to about 0.40% copper, and about 0.04% to about 0.35% chromium;
- the second hardness is about 100 in Brinell scale;
- wherein a thickness of the ball-striking face is reduced in order to reduce weight of the ball-striking face by at least 10 grams, wherein the at least 10 grams of weight is redistributed to move a center of gravity of the golf club head away from the ball-striking face and lower the center of gravity toward the bottom portion of the golf club head;
- wherein the golf club head is associated with a moment of inertia about a Y axis of the golf club head, the moment of inertia ranging from about 4100 g-cm2 to about 4300 g-cm2;
- wherein the golf club head is associated with a moment of inertia about an X axis of the golf club head, the moment of inertia ranging from about 800 g-cm2 to about 900 g-cm2;
- and
- wherein the golf club head is associated with a moment of inertia about a Z axis of the golf club head, the moment of inertia ranging from about 1100 g-cm2 to about 1200 g-cm2.
A golf club comprising:
- a shaft;
- a golf club head coupled to the shaft, the golf club head having a ball-striking face associated with a first hardness, the golf club head associated with a moment of inertia about a Y axis of the golf club head, the moment of inertia ranged from about 4100 g-cm2 to about 4300 g-cm2;
- and
- wherein the golf club head is associated with a moment of inertia about an X axis of the golf club head, the moment of inertia ranging from about 800 g-cm2 to about 900 g-cm2;
- wherein the golf club head is associated with a moment of inertia about a Z axis of the golf club head, the moment of inertia ranging from about 1100 g-cm2 to about 1200 g-cm2;
- a protective aluminum oxide layer coupled to the ball-striking face, wherein the protective aluminum oxide layer is associated with a second hardness, and wherein the second hardness is greater than the first hardness;
- the ball-striking face comprises, by weight, about 0.8% to about 1.2% magnesium, about 0.4% to about 0.8% silicon, about 0.15% to about 0.40% copper, and about 0.04% to about 0.35% chromium;
- the second hardness is about 100 in Brinell scale;
- wherein a thickness of the ball-striking face is reduced in order to reduce weight of the ball-striking face by at least 10 grams, wherein the at least 10 grams of weight is redistributed to move a center of gravity of the golf club head away from the ball-striking face and lower the center of gravity toward the bottom portion of the golf club head.
