Biomaterial

特許 権利維持 PROBLEM TO BE SOLVED: To provide a biomaterial having low rigidity, high strength, and excellent corrosion resistance. SOLUTION: The biomaterial contains a metallic glass alloy having a composition of formula: (Ti<SB>1-a-b-c</SB>Cu<SB>a</SB>Zr<SB>b</SB>Pd<SB>c</SB>)<SB>100-x</SB>M<SB>x</SB>(wherein a, b and c are atomic ratios: a is 0.3-0.5; b is 0.005-0.2, and c is 0.005-0.2; x is atomic percent and is 0.5-2 atomic percent; M is an element selected from at least one of HA, CaTiO<SB>3</SB>and CaZrO<SB>3</SB>).
