Titanium Alloy Ti6Al7Nb (UNS R56700) is a dedicated, medium-strength alloy for surgical implants. it is a 6% aluminum and 7% niobium containing alpha-beta phase Ti-Alloy. It has higher corrosion resistance and tolerance due to the added advantageous mechanical properties in relation to Ti-6Al-4V alloys. Ti6Al7nb alloy was developed specifically for the manufacture of femoral component items for hip prostheses. 

The metallurgy of Ti-6Al-7Nb Alloy is closely analogous to Ti6Al4V but biocompatibility is improved with the replacement of vanadium with niobium.

Ti6Al7Nb Alloy has high biocompatibility. The oxides from Ti-6Al-7Nb are saturated in the body and are not transported in vivo or are a bioburden. The alloy will not create adverse tissue tolerance reactions and creates fewer giant cell nuclei. Besides, Ti-6Al-7Nb shows high compatibility with ingrowth in the human body.
