However, aluminum is a reactive metal and non-magnetic, so adding the layers of steel gives you the best of both worlds.

But last time around, lower-end coolers used less-conductive aluminum for the baseplate ... and RM2 CPU cooler designs include copper baseplates. Intel Core Ultra (Series 2) CoolerLaminar RH2 ...
