A golf club head and a low density alloy thereof are provided. The low density alloy has a balanced weight percentage of titanium, 10˜11 wt % aluminum, and trace elements including (C+N+O) <0.2 wt %, silicon <0.2 wt %, and (Fe+Cr+V+Mo) <0.4 wt %. The golf club head has a tensile strength of 90˜110 kips/in2, and a density of 4.18˜4.30 g/cm3. Through heat treatment at a high temperature of 925±25° C., the precipitation or α2 phase of the interfacial interphase can be avoided, and thus the embrittlement phenomena can be improved. |
