Ti-6A1-7Nb WTF!?!?!

[Bruce Caulley]

Morning all,

 

We have been told to use this spec titanium on a medical component but cannot find a reference to this grade anywhere. Is there an equivalent, or can someone make some sense out of it? We are pretty certain that it isn't a typo.

From the little info I've dug up about it, it is definately used in the medical field as implant material

I have some books given to me with all the metals ever made . . . give me the details, and I will give you the "book" info . . .

 

What is yor application: milling, drilling, slab, side or slot milling, turning, etc.?

 

BTW, do a web site search:

Here is one medical usage and you will find more.

 

Touch base with me and I can help you with machining techneques

Thanks all. My bad. What I meant to ask was if anyone knew a supplier that had any. We have been trawling through the US EU and OZ looking and no-one knows anything about it. Looking at the links you have given me I now have an alternative ASTM spec that we can start asking for.

 

Thanks again.

The proper nomenclature is Ti-6Al-7Nb (367)

 

It is a dedicated, high-strength, titanium alloy with excellent biocompatibility for surgical implants. Used for replacement hip joints, it has been in clinical use since early 1986.

 

Ti = titanium

6Al = aluminum (5.5-6.5%)

7Nb = Niobium (6.5-7.5%)

 

Swiss National specification SN 056512

 

RHc 22-26

 

You can use higher feed and lower speed with lots of flood coolant on non-chlorinated cutting fluid. You can use water jet cutting, wire EDM and plasma cutting. Take care to avoid hydrogen, oxygen and nitrogen pick-up at exposed surfaces when performing machining, cutting or grinding operation.
