Copper is better but for most projects you'd never notice any difference. The best example of why copper is better deals with Lincoln SA 200 engine drives. Pipeliners noticed that on the machines made from about 73 with aluminum shunt coils, that the machines would heat up and not keep consistent amperage settings. They'd start off in the morning and after a couple hours have to turn their heat up. Then after they had lunch, the machines would be too hot and they'd have to turn them down again. For THIS application, the aluminum was a real PIA! So much so that Lincoln went back to all copper in the Classic and later pipeliner series machines. Price out a 200D pipeliner and you'll see they cost more than a larger non true DC generator machine.
