Tin Plated Copper Screws Okay for the Long Term?


2001

Do you think there may be a long term issue if copper screw plated with Tin.

I don't think so, I've been plating tin onto copper for years (it's part of the research I do), and some of my samples are still around, aside from a little oxidation they've not changed much. Your screws will, I assume, be doing more than sitting around a desk, so they might behave differently. In most conditions tin will galvanically protect copper, but then copper is not big on corrosion anyway.

Are you perhaps worried about intermetallic embrittlement? Which as far as I know doesn't happen.

Hope I've been some help.
