Beschreibung
Zusammenfassung:	Disclosed is a medical bone implant that is made at least in part of a titanium alloy having the following composition: 25 to 30 percent by weight of niobium; 0.5 to 3.0 percent by weight of iron and/or manganese; 0.1 to 1.0 percent by weight of silicon; and 66.0 to 74.4 percent by weight of titanium including inevitable impurities. Said titanium alloy can be produced as follows: an alloy ingot having said composition is smelted; the alloy is thermomechanically treated; the thermomechanically treated alloy is heat-treated; and the alloy is cold-formed into a martensitic structural state. The obtained titanium alloy is characterized by high tensile strength and a low modulus of elasticity.
