Overview

ISO 5832-3:2021 - "Implants for surgery - Metallic materials - Part 3: Wrought titanium 6‑aluminium 4‑vanadium alloy (Ti‑6Al‑4V)" - specifies the chemical, microstructural and mechanical characteristics, and the corresponding test methods, for wrought Ti‑6Al‑4V used in the manufacture of surgical implants. The standard applies to raw implant material; mechanical properties of finished devices may differ from the raw‑material values.

Keywords: ISO 5832-3:2021, Ti-6Al-4V, wrought titanium, surgical implants, implant materials, biomaterials.

Key topics and requirements

Chemical composition

Aluminium: 5.5–6.75%
Vanadium: 3.5–4.5%
Iron: ≤ 0.30%
Oxygen: ≤ 0.20%
Carbon: ≤ 0.08%
Nitrogen: ≤ 0.05%
Hydrogen: ≤ 0.015% (≤ 0.010% for billets)
Titanium: balance

Microstructure

Acceptable microstructure: equiaxed alpha or elongated primary alpha in a transformed beta matrix with no continuous alpha network at prior beta grain boundaries.
Transverse microstructures for round bars (annealed condition) are referenced to photomicrographs in ISO 20160 (A1–A9).

Mechanical properties (annealed condition)

Tensile strength (Rm): ≥ 860 MPa
Proof/yield strength (Rp0.2): ≥ 780 MPa
Elongation after fracture: ≥ 8% for sheet/strip, ≥ 10% for bars
Bend test: sheet/strip must withstand bending (105°) around a mandrel specified as 10 × t (t = thickness)

Test methods

Tensile tests: ISO 6892-1
Bend tests: ISO 7438
Microstructure classification: ISO 20160

Conformity & retest rules

Retest procedures and pass/fail criteria are defined (including provisions if failures occur inside/outside gauge length).

Applications and users

Practical use: provides material requirements for manufacturers of surgical implants (e.g., orthopaedic and dental implant components), raw material suppliers, medical device OEMs, quality assurance and testing laboratories, and regulators verifying material conformity.

Why it matters: ensures consistent biocompatible, high‑strength, corrosion‑resistant wrought Ti‑6Al‑4V raw material suitable for surgical implant fabrication and global trade.
