Due to its good overall performance and excellent corrosion resistance, industrial pure titanium makes it an indispensable structural material for many industrial parts. As a bio-implant material, it has been widely used in clinics since the 1960s. Among all commonly used implanted metal materials, titanium has good biocompatibility, and because its density and elasticity are close to human bones, and it is non-magnetic, titanium, titanium, cobalt chromium molybdenum alloy and titanium are the three major metal implant materials. It is the most promising bioengineering material. The application of titanium has solved many major engineering and technical problems, promoted scientific and technological progress, and brought obvious economic benefits, while the excellent performance and huge potential of titanium have demonstrated its broader prospects for application.
