Abstract: An iron type head body comprises: a material body 13 made from a forgeable metal; and a disparate metallic member 12 made from a metal having nearly equal or smaller specific gravity than the material body 13, and different constituents. By providing the disparate metallic member 12 inside the upper portion of the head body not adjacent to the sole, the head can be lightened. Moreover, by confining the disparate metallic member 12 in the portion upside of the sole 4 not adjacent to the sole 5, the head body 11 can be hypobaric, while the C.G. of the head 2 can be lowered entirely in addition to being lightened.

Abstract translation: 铁型头体包括：由可锻金属制成的材料体13; 以及由与材料体13几乎相等或更小的金属制成的不同的金属构件12，以及不同的构成。 通过将不同的金属构件12设置在头部本体的与鞋底相邻的上部内，可以减轻头部。 此外，通过将不同的金属构件12限制在不与鞋底5相邻的鞋底4的上部的部分中，头部主体11可以是低压的，而C.G. 头部2除了被点亮之外，可以完全降低。

Abstract: A method for manufacturing a golf club head with a disparate metallic material provided on a hosel side of the head, which can improve degree of freedom in the design of a head. A head body is made up of a columnar material body 13 made from a forgeable metallic material such as copper and a disparate metallic member 12 as an axial member. The disparate metallic member 12 has its proximal end 12A inserted into a bore 14 formed along a center of axis of the material body 13, while its distal end 12B protruded in the axial direction X. The material body 13 is placed on a lower die 22 which is formed with a mold 21 defining a contour of the head body 11, and then an upper die is pressed thereto. Thus, hot forging process is carried out to form a golf club head.

Abstract: A hollow iron clubhead having a low center of gravity and enabling free selection of a material for the clubface can be readily produced by press working. The hollow iron clubhead mainly comprises a clubface member, a front body member and a rear body member. A blank for forming the clubface member, a blank for forming the front body member and a blank for forming the rear body member are prepared by blanking. The clubface blank and the front body blank are integrally welded together and shaped by hot drawing to form the front body member. The rear body blank is shaped by hot drawing to form the rear body member. The front body member and the rear body member are integrally joined together by welding.
