Golf club heads with face plates of varying specific gravity

摘要

In a set of golf iron heads, at least part of the striking face of each head is of a material selected for characteristics desired for the particular iron in the set, and at least some of the heads are multi-component heads in which at least part of the striking face area of the head comprises at least one face-piece component of material having at least one characteristic different from the rest of the head. There is also provided a multi-component golf iron head in which at least part of the striking face area of the head comprises at least one face-piece component, the face-piece component being: (a) of material selected for its surface friction and/or flexural modulus characteristics affecting the spin behavior of golf balls when struck by the head, and/or (b) of specific gravity and/or geometric configuration selected to contribute to the desired weight distribution in the head.
