Tearing into my Chinapion (Champion) generator, I discovered that the windings on the rotor are a beautiful copper color, but in actuality the wire is made from aluminum (not sure about the stator). So - does this amount to a hill of beans and it's merely a blatant case of cost cutting, or are there real performance variances between CU and AL? I know that CU is a better conductor of electricity than AL, but do quality generators (Honda inverters) use copper? Do car alts use copper in their windings?

Only 12V flow throw rotor windings as measured at the brushes (normal).
