Biomedical Grade Pure Metals mainly include Titanium(Ti),Tantalum(Ta),Niobium(Nb),and Zirconium(Zr).
Ⅰ. Pure Titanium(Ti): Gr1,Gr2,Gr3,Gr4.
Ⅱ. Pure Tantalum(Ta):
Tantalum,one of refractory metals,has excellent biocompatibility,and therefore its biomedical applications mainly include:
1. cast pure tantalum;
cast pure tantalum is made for surgical implants in accordance with ASTM F560.
2. tantalum coating;
tantalum coating can improve biocompatibility and fatigue resistance of surgical implants,and therefore it usually is coated on the surface of other metallic biomaterials.
Tantalum coated metallic biomaterials set forth below:
◇Titanium;
◇Stainless Steel;
◇Cobalt Based Alloys;
◇Pure Niobium.
