Black Oxiding for Tin Electroplate?
I have a customer who is asking about setting up a black oxide line for tin-plated steel and brass wire. I have heard of blackening of tin, but not exactly black oxiding of such. Our products would impart, at best, a darkening (maybe brown, gray or blue-ish), but I doubt that it would be BLACK. Any ideas or knowledge on this? Thanks!
