Claims
- 1. A golf club head comprising:a body having a crown, a sole and a striking plate, the body having a hollow interior, wherein the golf club head has a moment of inertia, Izz, greater than 3000 g-cm2 and a moment of inertia, Iyy, greater than 1900 g-cm2, and each of the products of inertia, Ixy and Ixz, of the golf club head has an absolute value less than 100 g-cm2, and the product of inertia, Iyz, is greater than 0 g-cm2, wherein the moments of inertia and the products of inertia are defined by the vertical axis Z through the center of gravity of the golf club head, a horizontal axis Y through the center of gravity of the golf club head and substantially parallel to the striking plate, and a forward to rearward axis X through the center of gravity of the golf club head, the X axis, the Y axis and the Z axis are orthogonal to each other.

- 6. The golf club head according to claim 5 further comprising at least one weight strip composed of a material selected from the group consisting of a densified loaded film, copper, tungsten, and bismuth.
- 7. The golf club head according to claim 1 wherein the body is composed of a material selected from the group consisting of titanium, titanium alloy, steel, stainless steel, and amorphous metals.
- 8. The golf club head according to claim 7 wherein the striking plate has regions of varying thickness.
- 9. The golf club head according to claim 7 further comprising a plurality of weight members, the plurality of weight members having a total mass of less than 85 g.
- 10. The golf club head according to claim 9 wherein the body is composed of a titanium alloy material, the body having a mass less than 250 g.
- 11. The golf club head according to claim 1 wherein the product of inertia, Ixy, has an absolute value less than 50 g-cm2.
- 12. A golf club head comprising:a body having a crown, a sole, a ribbon and a striking plate, the body having a hollow interior, the body composed of a material selected from the group consisting of titanium, titanium alloy, steel, stainless steel, and amorphous metals; and at least one weight member disposed within the hollow interior of the body along the ribbon, wherein the golf club head has a volume ranging from 300 cm3 to 600 cm3, a moment of inertia, Izz, that ranges from 3000 g-cm2 to 5000 g-cm2, and a moment of inertia, Iyy, of at least 1900 g-cm2, and each of the products of inertia, Ixy and Ixz, of the golf club head has an absolute value less than 100 g-cm2, and the product of inertia, Iyz, of the golf club head ranges from 0 g-cm2 to 300 g-cm2, wherein the moments of inertia and the products of inertia are defined by the vertical axis Z through the center of gravity of the golf club head, a horizontal axis Y through the center of gravity of the golf club head and substantially parallel to the striking plate, and a forward to rearward axis X through the center of gravity of the golf club head, the X axis, the Y axis and the Z axis are orthogonal to each other.
- 13. The golf club head according to claim 12 wherein the striking plate has regions of varying thickness.
- 14. The golf club head according to claim 12 wherein the plurality of weight members have a total mass of less than 85 g.
- 15. The golf club head according to claim 12 wherein the body is composed of a titanium alloy material, the body having a mass less than 250 g.
- 16. The golf club head according to claim 12 wherein the product of inertia, Ixy, has an absolute value less than 50 g-cm2.
- 17. The golf club head according to claim 12 wherein a plurality of weight members are disposed within the hollow interior of the body along the ribbon.
