Pulled these out of old Dell servers. The "copper" colored ones I presume are copper. What about the "stainless" ones? They look the same as the copper, I weighed them in my hand and they seem to be about the same weight. So copper too? I just thought that copper has always the same color.

deep file test to expose base metals if plated

The ones that don't look like copper, but feel the same are plated. I think it is nickel or something along those lines. I always flip my stand grinder on and buff a little off so the scrap yard can see that they are indeed copper.

As your taking them apart the ones that feel the same just runn a screwdriver across it with a little pressure and you can see the copper quick and easy.

The silver ones are copper with aluminum fins soldered with silver solder. Heat with a torch and knock the fins out. The other one is pure copper, but they use silver solder to hold the copper fins to the base. So goes as number 2.

The ones that are silver colored are copper base and the fins are stainless steel unless they came out with aluminum that sparks when hit with a grinder.
