Introduction Tc20, the full name Ti6Al7Nb, is a new implant material with high technical content and high economic value, which has the excellent comprehensive performance required for orthopedic implant products. The standards implemented by different countries and regions include: ISO5832-11, ASTM F1295, GB/T13810, GB 23102. The material was developed by Swiss Sulzer Medical Technology Co., Ltd. in 1977. After 8 years, it was successfully developed and clinically applied in 1985. In 1985, the development report of the surgical implant material Ti-6Al-7Nb alloy was published in Paris. At...

Composition Chemical Composition (mass %) Molecular Structure Internal Fibrous Tissue The difference between TC 20 and TC 4 Tc20 (Ti6Al7Nb) and TC4 (Ti-6Al-4V) belong to α+β titanium alloy. The main difference is that TC20 replaces the toxic element vanadium (V) in TC4 with non-toxic element (Nb). The advantages of this difference 1.It can eliminate the potential cytotoxicity and has better corrosion resistance and histocompatibility than TC 4. 2.The Nb element can promote the increase of the density of the passivation film formed by the Ti-6Al-7Nb alloy when the surface is oxidized, so...

Excellent Properties Excellent comprehensive mechanical properties Static mechanical properties tensile strength Non-proportional extension strength Elongation after break Dynamic mechanical properties Impact toughness breaking tenacity High temperature plasticity The stress amplitude of a particular cycle Good Note: the stress amplitude at 10 million cycles is considered as the fatigue limit, which is the maximum stress that the sample can withstand infinite cycles without failure. The test results show that TC20 has excellent anti-fatigue characteristics WUHAN YIJIABAO BIOLOGICAL...

Excellent corrosion resistance Photo caption: polarization curves of Ti6Al7Nb, Ti6Al4V and pure titanium in hydrochloric acid solution at 37 ℃ and 2mol, respectively. The results show that the corrosion resistance of Ti6Al7Nb in reducing environment is better than that of Ti6Al4V. Photo caption: pitting potential data of Ti6Al7Nb, Ti6Al4V and pure titanium in 2mol hydrochloric acid solution at 37 ℃ respectively. The results show that the passivation film of Ti6Al7Nb is more resistant to corrosion than Ti6Al4V in strong reducing environment. WUHAN YIJIABAO BIOLOGICAL MATERIALS CO., LTD

Excellent Biocompatibility The Institute of Physical Experiments at the University of Lausanne concluded that the oxides and hydroxides of titanium, aluminum and strontium in biological tissues have reached saturation, so that the dissolved metals in the implant are not ionized or transferred within the organism. Therefore, the constituent elements of the Ti6Al7Nb alloy do not create an additional physiological load, which is one of the reasons for its excellent biocompatibility. Histological examination of the slotted Ti6Al7Nb alloy disc on the back of the mouse at 1 week, 3 weeks and 9...
