Classification of medical titanium alloys

Grade 5 Ti-6Al-4V Titanium Bar can be divided into α-type titanium alloys (such as pure titanium series), α+β-type titanium alloys (such as Ti6Al4V, etc.), β-type titanium alloys (such as Ti12Mo6Zr2Fe, etc.) and TiNi shape memory titanium alloys according to the type of material microstructure. There are four types of alloys. Compared with medical stainless steel and cobalt-based alloys, they have the characteristics of small specific gravity, high specific strength, low elastic modulus, corrosion resistance, easy cutting and good biocompatibility.

According to professional standards for surgical implants and orthopedic devices, titanium alloy materials can be classified as "metal materials" in "materials for surgical implants", while Titanium Threaded Forged Fitting materials are used in non-active surgical implants and active surgical implants. In the three major categories of medical devices, implants and orthopedic devices, they can serve as cardiovascular, bone and joint, bone joint, spine, orthopedic devices, cardiac pacemakers and defibrillators, cochlear implants, neurostimulators and other implants The raw material of the product.
