      Could be plated copper, unless you have better information - I’ve seen similar components in breaker panels and the like that are plated copper (plated because raw copper likes to corrode and get ugly looking).

        I have just worked with aluminum pieces in a machine shop enough to spot em. I would be shocked if they were plated copper and not just aluminum.
