Abstract:
An improved high-modulus, low-cost, castable, weldable titanium alloy and a process for making such an alloy is provided. In general, titanium is alloyed with about 0. 75 weight percent iron and about 8 weight percent aluminum to result in an alloy with a modulus of over 21. times. 10. sup. 6 psi. This modulus is above the modulus for conventional castable titanium alloys, such as the commercially-available castable titanium alloy containing 6 weight percent aluminum and 4 weight percent vanadium.
Applications for this alloy include golf club heads, which can be fabricated by casting a golf club head body from the above alloy and welding a sole plate onto the cast golf club head body. This provides a golf club head with superior energy transfer characteristics for hitting a golf ball.
