Alloy 715 finish 1

[RvL04]

Hi;

I have almost no experience with material finishes on metal. Our customer needs a finish of 125 microinches (or better) on Alloy 715. This is a 70-30 Copper-Nickel alloy. Does anyone know if that alloy can get that finish, and if so, by what method(s)? Finally, does anyone know any commercial shops that do a good job with this kind of request?

Thanks very much!

Ron

By the way, I know of a variety of means to do this on steel (milling, drilling, sawing, chemical milling, forging), but I mainly need to know whether it can be done on this particular alloy. Thanks!

This polishes beautifully to an optical finish with Hyprez or Engis Diamond Lapping compound. If you haven't done it before I'd sub- con it though, it's a skilled task.

Alternatively, Single Point Diamond Turning (well, flycutting for flats actualy) will get an optical finish too.

Hope this helps
