Titanium-aluminium-tin alloy applied to golf club head

Abstract

A titanium-aluminum-tin alloy applied to a golf club head includes 89 wt % to 95 wt % titanium (Ti), 3.5 wt % to 6.5 wt % aluminum (Al), and 1.5 wt % to 3.5 wt % tin (Sn), and minor elements such as niobium (Nb), vanadium (V), molybdenum (Mo), zirconium (Zr), chromium (Cr), iron (Fe), silicon (Si), oxygen (O), and nitrogen (N) may be selectively added into the titanium-aluminum-tin alloy, so as to form a material with a high elongation from 11% to 15% and a tensile strength from 700 Mpa to 950 Mpa, which can be applied to a main body and a hitting surface of a golf club head, thereby achieving a golf club head product with good hitting sense, desirable damping capability, expected golf-controlling capability and a customized feature of an adjustable angle at a club portion, together with the internal structural designs of the main body, weighting structure, and rib design.
