Material help !!!! High hardness - non ferous material???

Material help !!!! High hardness - non ferous material???

Material help !!!! High hardness - non ferous material???

(OP)
I am looking for a material to try and suit all of my customers specs.  They would like to see something non-ferrous which can be hardened to Rc-60.  I don't think anything like this exists (and is readily available) so I am trying to come up with the next  best thing.  Any ideas?  I thought about 440c stainless but it's magnetic, or AMPC0-25 gets me Rc40 ish I think.

Hmmm I hadn't thought of that but I don't think it will work in my case.  The parts I need to make are going in some weld tooling. Can you machine ceramics the same was you can a metal? (I'm not sure if that a dumb question or not)

RE: Material help !!!! High hardness - non ferous material???

Why do you need this hardness for weld tooling? Do you just need surface hardness at 60 HRc?

RE: Material help !!!! High hardness - non ferous material???

Anodizing on aluminium alloys can approach that hardness level.

A better bet would be a titanium alloy that has the surface hardened (e.g. nitrogen diffusion hardening, diamond-like coating, etc.).

Do you have the option of hard chrome plating? If you do, you could plate the Ampco 25. Hard chrome is well in excess of Rc 60.

If you need bulk harness look at Brush Wellman.  My favorite is Be-Ni, but there are a bunch of age hardening Cu bassed alloys that will get you close.

Thanks for all your responses!  I'm going to see if my customer will budge on any of there specs so I can use a more basic material.  I only need the high hardness in weld tooling because my customer requires it.  It has to be non ferrous so it will not affect the weld schedule.
