Ti-6Al-7Nb
Ti-6Al-7Nb contains 6% aluminum and 7% niobium, which was developed as a biomedical replacement for Ti-6Al-4V alloy because Ti-6Al-4V contains vanadium, an element that has demonstrated cytotoxic outcomes when isolated.
Ti-6Al-7Nb is a dedicated high strength titanium alloy with excellent biocompatibility for surgical implants.
Ti-6Al-7Nb alloy is double or triple vacuum melted to provide an ingot composition that is very uniform and homogeneous. The ingot is hot pressed, and finished into round and flat bar products using conventional titanium alloy processing methods.
