Full title and description

St AS 2320.3-2003 (reconfirmed 2014) — Implants for surgery — Metallic materials — Part 3: Wrought titanium 6‑aluminium 4‑vanadium alloy. Specifies the required chemical, microstructural and mechanical characteristics and the corresponding test methods for wrought Ti‑6Al‑4V alloy intended for use in the manufacture of surgical implants.

Abstract

This part of AS 2320 sets out material requirements and test procedures for wrought titanium‑6Al‑4V intended as raw material for surgical implants (not finished devices). It is technically identical to ISO 5832‑3 and covers representative heat analysis, microstructure requirements, mechanical property limits and accepted test methods to verify conformity.

General information

• Edition / version: 2nd edition (AS 2320.3-2003), reconfirmed 30 May 2014.
• Number of pages: 2 pages (concise material specification).

Scope

Specifies the chemical composition ranges, microstructural characteristics and mechanical property requirements for wrought titanium 6‑aluminium 4‑vanadium alloy used as raw material in surgical implants, together with the corresponding test methods for verification. The standard applies to the material as supplied for manufacture of implants rather than to finished, processed implant assemblies. It is technically identical to ISO 5832‑3 (1996) as adopted by Standards Australia.

Key topics and requirements

• Chemical composition limits for Ti‑6Al‑4V (limits for Al, V and permitted impurities such as Fe, O, C, N, H).
• Microstructure requirements (acceptable alpha/beta microstructures and absence of detrimental continuous networks).
• Mechanical property criteria (tensile strength, yield/proof stress, elongation) and sampling/test-piece requirements.
• Test methods and reporting requirements (heat analysis, tensile testing, bend testing, hydrogen measurement where applicable).
• Conformity assessment for supplied raw material (how test results are to be declared and supplied to manufacturers of implants).

Typical use and users

Used by manufacturers and suppliers of raw implant materials, medical device manufacturers (orthopaedic, dental and other implant producers), materials laboratories performing acceptance testing, regulatory/compliance teams and standards committees developing or harmonising implant material specifications.

FAQ

Q: What is this standard?

A: AS 2320.3‑2003 is an Australian Standard (Part 3 of AS 2320) that specifies material and test requirements for wrought titanium 6‑aluminium 4‑vanadium alloy used in surgical implants; it adopts the corresponding ISO requirements.

Q: What does it cover?

A: It covers chemical composition ranges, microstructure descriptions, mechanical property limits and the test methods used to verify that supplied wrought Ti‑6Al‑4V material meets the requirements for use in implant manufacture.

Q: Who typically uses it?

A: Material suppliers, implant manufacturers, testing laboratories, and regulatory or quality teams involved in specifying, procuring or certifying implant‑grade titanium raw material.

Q: Is it current or superseded?

A: AS 2320.3‑2003 was reconfirmed in 2014 but has since been superseded by AS ISO 5832.3:2023 (the consolidated adoption of the later ISO edition). Check the national standards catalogue for current status and the precise effective/supersession dates.

Q: Is it part of a series?

A: Yes — it is Part 3 of the AS 2320 / ISO 5832 series “Implants for surgery — Metallic materials,” which includes parts covering stainless steels, unalloyed titanium and various cobalt‑chromium alloys (ISO 5832 series).

Q: What are the key keywords?
