Materials: TC20     Full Name: Ti6Al7Nb
It is a new type of implant material with high technology content and high economic value. Standards implemented in different countries and regions include: ISO5832-11, ASTM F1295, GB/T13810, GB 23102.

TC20 VS TC4

Differences between TC20 and TC4
TC20 (Ti6Al7Nb) and TC4(Ti-6Al-4V) belong to alpha + beta-titanium alloy. The main difference is that TC20 uses the non-toxic element niobium (Nb) instead of the toxic element vanadium (V) in TC4.

Advantage of Difference

1. The potential cytotoxicity of element V is eliminated and the material has good cytocompatibility.
2. Nb element can promote the density increase of passivation film formed by surface oxidation of ti-6al-7nb alloy, so that the material has good corrosion resistance.
3. The oxides and hydroxides of titanium, aluminum and niobium have reached saturation, and the dissolved metals in the implants will not be ionized or transferred in the body, making them have good biocompatibility.
