Proposed new ASTM WK35394 specification for MIM commercially pure Ti components for implant applications
March 14, 2012
A proposed new specification for ASTM WK35394, relating to metal injection moulded (MIM) commercially pure titanium components for surgical implant applications, is under development.
The specification covers the chemical, mechanical, and metallurgical requirements for four different grades of metal injection moulded commercial titanium components from unalloyed titanium and Titanium-6Aluminum-4Vanadium powders, for use in the manufacture of surgical implants. There are two types of materials within these four grades, as-sintered or with an additional densifying process such as hot isostatic pressing (HIP).
The Standard will use the nomenclature of the ASTM F 2885 Standard Specification for MIM Ti-6A-4V components for surgical implant applications and the chemical values of the ASTM F67 Standard Specification for unalloyed titanium for surgical implant applications demanded by the medical device industry in order to use CP Ti MIM parts for implantable applications.
The title and scope are in draft form and are under development within the ASTM Committee F04.12.
