Vitallium

[Ricardo Rios Jordana]

Does anyone know where to buy the Cobalt-Chromium-Molybdenum alloy,
also named Vitallium, used in orthopaedic applications (knee protheses), in
bar form?
Than you in advance

I hope that vitallium is only used outside the body.
If not maybe that's why my friend had to have a plate removed last week.
I haven't seen the plate yet but she says it feels kind of light weight.
Does titanium sometimes cause an allergic reaction too?

I cant comment on vitallium but can comment on titanium.
Pure titanium is used inside the body and the standard alloy TI V4A6 is
also used in body jewellery and jawbone implants to support crowns in
dental work. I use pure titanium in my body jewellery work and it has
many advantages over other metals. your friend probably had titanium and
its use was not intended to be a permanent installation.

Vitallium (R) is a registered trademark licensed to Austenal,Inc.
by Howmedica, Inc.

I get the general impression that it isn't sold as bar stock for
unsupervised applications. However, trying Thomas Register may still
turn something up.

Otherwise, you will probably need to deal with Howmedica Inc. They are
very proud of their family of implant metals, and are likely to be
cautious in just who gets to experiment with them in bulk. The econimic
interests are easy to understand.

AFAIK no

That's why it is used for implants more and more.

Vitallium is a very old alloy dating from the 30's and
developed by Austenal Laboratories which became part of
Howmet and is now part of Alcoa. A more generic name for
Vitallium is F75 and there are many variations, made by many
companies. Howmet and Cannon-Muskegon both make large
quantities of horizontally continuous cast bar stock
suitable for remelting. I don't know any suppliers of bar
stock ready for forging.

There are many prosthetic manufactures that use the
material. I was some what involved in helping develop a
vacuum version of the alloy a number of years ago and have
been involved in making both cobalt and titanium based hip,
knee and other implants until our company got of the that
business over 10 years ago.
