Low Elastic Modulus Of Pure Titanium And Titanium Alloys

Pure titanium and titanium alloys have a low modulus of elasticity (about 100 GPa), which is only 1/2 that of steel, and a high yield strength, which makes them useful for springs and golf club heads.

Modulus of Elasticity and Yield Strength Range of Various Metals

Golf club head bodies are generally made of Ti-6Al-4V using investment casting casting; SP700 (Ti-4.5Al-3V-2Mo-2Fe) and 15-5-3 (Ti-15Mo-5Zr-3Al) titanium alloy striking faces. The report states that players can increase the distance of their shots by an average of 20% when the head is changed to titanium. If the choice of lower modulus of elasticity of titanium alloy springs, in the same number of turns of the elasticity of the consideration, titanium springs than steel springs, titanium springs weight is only 28% of the steel springs, which can save energy and improve speed, such as springs advanced F1 racing cars and motorcycles are made of titanium alloys.
