Abstract
A titanium alloy includes 15 to 27 atomic % (at %) of tantalum (Ta) and 0 to 8 at % of tin (Sn), the balance being titanium (Ti) and unavoidable impurities, when the entire amount of the titanium alloy is taken as 100 at %. Therefore, the titanium alloy provided has characteristics suitable for medical device materials, biocompatible materials, etc.
Claims8
A titanium alloy for a living body, consisting of:
- 15 to 27 atomic % (at %) of tantalum (Ta);
- and
- 1 to 8 at % of tin (Sn) with the balance being titanium (Ti) and unavoidable impurities, when an entire amount of the titanium alloy is taken as 100 at %;
- wherein the titanium alloy has a Young's modulus of 40 Gpa or lower and a tensile strength of 800 MPa or larger and
- a value obtained by dividing the total atomic % of the tantalum and the tin by the total atomic % of the titanium and the unavoidable impurities is within a range of 0.34 to 0.36 within which the titanium alloy has both at once a maximum tensile strength and a minimum Young's modulus.
