How dangerous is it to work with beryllium copper alloy C17200?
I’m a watchmaking student, i want to make my own balance wheels, beryllium copper is known to be one of the best alloys for this purpose, how dangerous would it be to work with it on a lathe? Would i have to wear a dust respirator? What about skin contact? How should it be properly handled?
Thanks for any help.
Toxicity problems with beryllium copper are mainly due to long-term dust exposure. Skin contact is no problem unless you’re allergic. Lathe work should be no problem without protective gear beyond safety glasses. I’d wear a dust mask if I was grinding/sanding on it in any quantity but watchmaking sizes of metal should be no hazard at all. The beryllium in the alloy isn’t soluble, so a cut from it is just a cut.
