Used to do a lot of electroplating at a previous shop, now we work with cadmium and Nitrided surfaces, some times beryllium copper coatings and even machining BeCu parts which means a tyvex suit and respirator. I see you advertise BeCu spring BlueSwordM so Im sure you are familier with the side effects from that nasty material. Been trying to get a de-anodized A6 to be Cadmium coated but no luck so far haha. Might be able to sneak it through on the Nitriding rack though one day.
