Classification and characteristics of biomedical titanium alloy materials
2023 02/10
Biomedical titanium alloy materials refer to a class of functional structural materials specifically used in biomedical engineering, mainly used in the production and manufacture of surgical implants, orthopedic instruments and other products. According to the professional standards of surgical implants and orthopedic instruments, titanium alloy materials can be classified into the category of "metal materials" in "materials for surgical implants", while titanium alloy materials can serve as cardiovascular, bone and joint, bone joint, spine, orthopedic instruments, cardiac pacemakers and defibrillators, cochlear implants Raw materials for nerve stimulators and other implant products. Biomedical titanium alloys can be divided into α Type I titanium alloy (such as pure titanium series) α+β Type I titanium alloy (such as Ti6Al4V) and β Type II titanium alloys (such as Ti12Mo6Zr2Fe, etc.) and TiNi shape memory titanium alloys have the characteristics of small specific gravity, high specific strength, low elastic modulus, corrosion resistance, easy machining and good biocompatibility compared with medical stainless steel and cobalt-based alloys.
