But just to further the conversation on the subject, finished parts made from BeCu are considered inert and safe for contact, in my industry. I have been told by some shops that process those parts that chips and curls generated from milling and turning can be treated the same, as they can't be respirated, and skin contact is not considered an issue. They emphasize it is only the Be dust generated by abrasive operations which creates the noted health hazard. But take that for what you paid for it, this isn't my area of expertise, I'm just repeating what I've been told.
