ISO 5832-2 — Unalloyed titanium for surgical implants
Also known as: ISO 5832-2 titanium
Specifies the composition and mechanical properties required of unalloyed (commercially pure) titanium used to make surgical implants.
What it covers
What it means in practice
When a manufacturer states that a fixture is made to ISO 5832-2 Grade 4, it is telling you something concrete and checkable. When it says "medical grade titanium", it is not — there are four unalloyed grades of differing strength plus several alloys, and the phrase covers all of them. This is one of the few places where a specification citation genuinely separates careful documentation from marketing.
