use

Because of its good comprehensive performance and excellent corrosion resistance, industrial pure titanium has become an indispensable structural material in many industrial parts. As biological implant material, it has been widely used in clinic since 1960s. Titanium is the most promising bioengineering material in stainless steel, cobalt-chromium-molybdenum alloy and titanium implants because of its good biocompatibility and its density and elasticity close to human bone and non-magnetic properties. The application of titanium has solved many important engineering and technical problems, promoted the progress of science and technology, and brought obvious economic benefits, and the excellent performance and huge potential of titanium, and showed a broader prospect of its application.
