Metal materials implanted into human or animal bodies to repair organs and restore function are called biometallic materials. At Present, the main Biometallic Materials include: Stainless Steel(Fe-18Cr-12Ni-2Mo), Titanium and its alloy, Co-30Cr-6Mo alloy.
1.Stainless Steel's corrosion resistance and strength is not as good as cobalt chromium molybdenum alloy, but the price is cheap and the processing performance is good, so it is the most used in medical treatment. Stainless steel is mainly used to make bone plates, bone hooks, bone screws and other parts for fixing fracture sites, and is also used to make artificial bones and artificial joints. The typical alloy of stainless steel used in orthopaedics is Fe-18Cr-12Ni-2Mo.
2.Medical titanium is a type of titanium that is specifically designed for use in medical devices and implants. It is known for its high strength, low density, and excellent biocompatibility, making it an ideal material for surgical implants. Medical titanium is commonly used in orthopedic implants, such as hip and knee replacements, as well as dental implants and surgical instruments. Its biocompatible nature allows for the bone to grow and adhere to the implant, creating a strong and stable connection.
3.This cobalt-based alloy is often called Vitallium. Its typical composition is Co-30Cr-6Mo, which also contains 0.35% carbon. Its corrosion resistance is about 40 times higher than that of stainless steel (Fe-18Cr-12Ni-2Mo), and has excellent fatigue resistance and wear resistance, which is the best orthopedic alloy material at present. The role of chromium and molybdenum in the alloy is to improve the strength and corrosion resistance. Molybdenum can also prevent grain growth during crystallization, thereby improving fatigue resistance. The disadvantage is high hardness and difficult processing.
Ti-1262 Ti-12Mo-6Zr-2Fe Bar & Wire ASTM F1813
Ti12Mo6Zr2Fe is a BETA titanium alloy without Vanadium developed for orthopaedics. Its properties allow excellent mechanical properties, a low elasticity modulus, a good corrosion and fatigue resistance, besides a good durability. Furthermore, the absence of Aluminium and Vanadium makes it a good biocompatibility.

NiTi Shape Memory Alloy (SMA) Wire
Nitinol Wire is a nickel-titanium alloy with super elasticity and shape memory properties. Shape memory refers to the ability of Nitinol to undergo deformation at one temperature, then recover its original, under formed shape upon heating above its transformation temperature. Super elasticity occurs at a narrow temperature range just above its transformation temperature; in this case, no heating is necessary to cause the under formed shape to recover, and the material exhibits enormous elasticity, some 10-30 times that of ordinary metal.

NiTi alloy sheet ASTM F2063
The Nitinol sheet is a unique form of shape memory alloys because its shape allows for additional design opportunities. Unlike wire and tube, the sheet is a two-dimensional structure, which overcomes a set of design obstacles. Additionally, a flat NiTi sheet allows designers to perform operations that cannot be done with wire or tube, such as stamping, drilling, and deep forming. The Nitinol sheet is the manufacturing product of the nickel-titanium alloy.
