ISO 5832-3 — Wrought titanium 6-aluminium 4-vanadium alloy for surgical implants
Also known as: Ti-6Al-4V standard, ISO 5832-3 alloy
Specifies the composition and properties of the Ti-6Al-4V titanium alloy used in surgical implants.
What it covers
What it means in practice
Ti-6Al-4V is stronger than unalloyed titanium, which is why it appears in components that carry concentrated load. It contains aluminium and vanadium, and that composition is occasionally raised as a concern by patients seeking metal-free or minimally-alloyed options. The evidence position is that the alloy has a long clinical history in orthopaedics and dentistry; the point worth making is simply that "titanium" covers both this and the unalloyed grades, and they are not the same material.
