Medical titanium and titanium alloy are high quality metal materials, widely used. Titanium and titanium alloys have excellent application characteristics and are recognized as excellent metal materials in the medical field in the world. Compared with the use of stainless steel, cobalt base alloy and other metal materials, titanium and titanium alloys have greater application advantages. According to the above table, it is not difficult to see that titanium and titanium alloys have obvious advantages in specific strength, elastic modulus, corrosion resistance and corrosion fatigue resistance.
Established due to trauma, tumor and other factors lead to damage of bone and joint bone scaffold, must with the aid of arc plate, screw, artificial bone and joint, etc., these implants will leave the body for a long time, will be affected by the bending and torsion of the human body, extrusion, the action such as muscle contraction force, the characteristics of titanium and titanium alloy high strength and toughness good natural wait for ages.
Because titanium is resistant to corrosion, that means it's chemically stable, resistant to fluid corrosion, and suitable for use in all body parts.
Titanium has good biocompatibility. Titanium and titanium alloy are known as bioinert metal materials, which have excellent abrasion resistance for human blood immersion environment and ensure good compatibility with human blood and cell tissue.
Titanium is an ideal artificial joint material
Artificial joint and artificial bone replacement materials should have the following basic properties: light weight and high strength materials, with biological compatibility, corrosion resistance, the tissue reaction of the implant in the body does not cause the deterioration of materials, repeated stress caused by fatigue, less damage and other properties.
The most important properties of metal implants are formability, machinability, and polishing properties, which must be maintained over the expected life of the implant and not degraded during fatigue, wear, corrosion, and impact loading. Titanium and titanium alloys meet all of the above requirements.
