A weighted part of a golf club head is provided. The compositions of the weighted part by weight percent are 12% to 15% iron, 11% to 13% chromium, 25% to 30% tungsten, and some nickel. The alloy for the weighted part has the advantages of being heavier than stainless steel and titanium alloys in weight, enjoying higher tensile strength, providing higher plastic deformation for the weighted part, and forming more complicated trademarks or patterns directly at specific locations during weighted part formation. In addition, the mechanical properties of the weighted part of a golf club head can be improved by adding ingredients including carbon below 0.01%, 0.1% to 0.6% silicon, manganese below 0.01%, phosphorus below 0.01%, sulphur below 0.01%, and copper below 0.01%.
