This came from a friend, but I couldn't answer, so I thought of the TechNet search engine. Can "you guys" suggest a source of information to answer this question?
I've got a strange situation. The contents of a steel enclosure were recovered after a large fire. The copper and brass components were melted and fused. BUT the spiral foil from a capacitor survived inside the same steel box. I ASSUMED it was aluminum which creates a nasty conundrum: copper melts at 1860F, Aluminum at 1180F. BUT I've been informed (to my chagrin) that "newer high quality" capacitors use a nickel chromium alloy foil - do you have any experience with this?? A quick Google search didn't turn up any immediately recognizable information...
Thanks,
Carl
