A method for manufacturing a golf club head includes aging heat treat a sheet material made of a titanium alloy at 650-750° C. for 10-12 hours to obtain an aging heat treated sheet material. The aging heat treated sheet material is hot rolled to form a striking plate. The striking plate is annealed at 700-800° C. for 30-60 minutes to obtain an annealed striking plate. The annealed striking plate is welded to a club head body made of the titanium alloy to form a semi product. The semi product of the golf head is annealed at 500-700° C. for 30-240 minutes to obtain the golf club head. Thus, the golf club head with a Young's modulus higher than 119 GPa can be manufactured.

A method for manufacturing a golf club head includes providing a club head body produced by electric smelting an alloy base material including 0.04-0.07 wt % of carbon, 0.5-1.0 wt % of manganese, 0.5-1.0 wt % of silicon, less than 0.04 wt % of phosphorus, less than 0.03 wt % of sulfur, 15-17.7 wt % of chromium, 3.6-5.1 wt % of nickel, 2.8-3.5 wt % of copper, with the rest being iron and inevitable impurities. A solid solution treatment is proceeded at 1020-1080° C. for 80-100 minutes to form austenite and martensite in the club head body. A deep cooling treatment is proceeded between −120° C. and −80° C. for 7-9 hours to turn the austenite in the club head body into martensite. An aging treatment is proceeded on the club head body at 460-500° C. for 210-270 minutes to provide a hardness of HRC 36-46. A hosel is heated with high frequency waves at 900-1000° C. to posses a hardness lower than HRC 20.

A method for manufacturing a golf club head having an embedded heterogeneous material includes preparing a shell mold having a cavity and a functional member embedded into the shell mold via an embedded portion, filling the cavity with a metal liquid to completely dip the non-embedded portion of the functional member in the metal liquid; breaking the shell mold to obtain a cast product, separating the golf club head cast member from the cast product to obtain a semi-finished golf club head having a casting material and a heterogeneous material, and pressing the casting material of the semi-finished golf club head to securely engage the casting material with the heterogeneous material. The functional member includes a non-embedded portion connected to the embedded portion and located in the cavity. The cast product includes a golf club head cast member.
