Titanium alloy TC4 and TC4ELI

Titanium alloy TC4α-β titanium alloy containing 6% α-stable element and 4% β-stable element V. The nominal composition of TC4 titanium alloy has an Al equivalent of 7.0 and Mo equivalent of 2.9, and the annealing state contains 10%-15% β phase. In Ti-Al-V system, Al improves the strength and thermal strength at room temperature by strengthening α phase in solution, while V is one of the few alloy elements that can improve both strength and plasticity. Titanium Tube Supplier says V has a favorable effect on titanium alloy plasticity because it does not increase the c/a axis ratio of the α-state lattice, as most alloying elements do, but decreases the ratio, thereby improving the formation of the α phase and avoiding embrittleness of the alloy during long term use. TC4ELI titanium alloy is an improved version of TC4, its main difference is different Al content and lower content of gap elements Fe, N, H, O. TC4ELI has the advantages of good compatibility, low density, good anti-corrosion performance, non-toxic, high yield strength, long fatigue life, large plasticity at room temperature, easy to form and become the ideal material for medical surgical implants. Medical TC4ELI titanium alloy plate is mainly used for skull repair, bone grafting and other aspects, which has higher requirements for its strength, fatigue life, plasticity and so on. TC4 ELI titanium alloy on the basis of TC4 alloy, the content of gap elements C, O, N and impurity elements Fe is reduced, the strength is reduced, but the toughness can be significantly improved. TC4 ELI has good plasticity, toughness, good welding performance and low temperature performance, widely used in cryogenic engineering, medical, ships and aircraft and other important fields. TC4 alloy can be used in ordinary environment or high temperature environment, TC4ELI alloy can be used in ultra-low temperature environment TC4 titanium alloy and TC4ELI titanium alloy similar grades are: T-6A-4V/Grade 5 (American grade), BT 6 (Russian grade), IMI 318 (British grade), TiAI6V4 (German grade).
