Description of ASTM F136 Medical Titanium Implant Bar

The commonly used grades of medical titanium alloys are Ti-6Al-4V and Ti-6Al-4V ELI, but because the metal vanadium is harmful to the human body, it is replaced by the non-toxic and stable metal niobium.

ASTM F136 Medical Titanium Implant Bar has good toughness, plasticity, and high temperature deformation properties, high temperature strength, high compatibility with the human body, good impact resistance, good corrosion resistance, long service life, and so on. They work under high temperature and high pressure for a long time, and the strength after heat treatment is about 50%-100% higher than that after annealing.

Application of ASTM F136 Medical Titanium Implant Bar
