At present, most medical steels are made of titanium alloy, which has good compatibility with tissues, and the strength of steel is high and the cost is relatively high.
Medical titanium alloys are used to manufacture titanium alloys for medical devices, prostheses or artificial organs and auxiliary treatment equipment implanted in human bodies. There are mainly titanium 6 aluminum 4 vanadium, titanium 5 aluminum 2.5 tin and other alloys. They have the characteristics of high specific strength, mechanical properties close to human bones, far superior strength to pure titanium, fatigue resistance, corrosion resistance and excellent biocompatibility.
