Bio-Medical Grade Titanium and its Alloys:

Properties of Medical Grade Titanium:

     1. high strength-to-weight radio(low density、high strength);

     2. high corrosion resistance(naturally form a layer protective oxide film on surface of Titanium and its alloys);

     3. good biocompatibility(osseointegration);

     4. low modulus of elasticity(approximately half of other biometals,clear to natural human bone);

     5. non-magnetic(not susceptible to outside interference);

     6. easy worked(can be machined a great many product forms);

     Compare with other biometals,two of the greatest properties of natural titanium are its high strength-to-weight radio and corrosion resistance.    Coupling this with its extra biocompatibility,osseointegration,flexibility and formability,titanium has become the ultimate metallic materials of biomedical choice for surgical implants and instruments,medical devices and equipment,prosthetic components and orthotic devices,and other medical fields.
