Abstract
A composite material integrally forged iron head of a golf club includes a head body, a weight part and a cover. The head body has an engaging recess formed inside. The weight part is mounted in the engaging recess and the material of the weight part is composite ceramics and has a density of 1.3 to 3.5 g/cc. The cover is welded on the engaging recess of the head body, and the weight part is sealed by the head body and the cover without any gap. The integrally forged iron head has a lower density in the center and a higher density in the surrounding area, which increases the error tolerance and enlarges the sweet-spot area, and also improves the sound and feel of striking.
