Biomedical materials are those that interact with biological systems, are used to diagnose, treat repair, or replace tissues, and organs, or enhance functions in an organism. It can be divided into medical metal materials, medical polymer materials, medical ceramic materials, etc., among which, medical metal materials occupy a large proportion, especially orthopedic products, and cardio-cerebrovascular products.
Due to the proximity of titanium to human bone, It has good biocompatibility with human tissues, no toxic side effects, with advantages that are not comparable to other materials, so medical titanium has been widely used in the medical field.
★Biocompatibility: It has a minimal biological reaction with the human body and is non-toxic and non-magnetic. As a human implant, it has no side effects on the human body.
★Mechanical properties:
With high strength and low elastic modulus, it not only meets the mechanical requirements but also is similar to the elastic modulus of human natural bone, which can reduce the stress shielding effect and is more conducive to the growth and healing of human bone.
★Corrosion resistance:
Titanium alloy is a bio-inert material, which has intentional corrosion resistance in the human physiological environment and does not pollute the human physiological environment.
★Lightweight: generally, the density of titanium alloy is only 56% of that of stainless steel. After being implanted into the human body, the load of the human body is greatly reduced.
