  • Different coloured copper

    I have some copper wires from motors which are slightly different colour. Some is almost orange and some the more rusty colour i am used to. Is it a lower quality?

  • #2
    If it's all copper then it all goes as the same, #2 copper or burnt copper.
    if it's very bright and clean then it's milberry and about 40c kg more but all that will be #2

    the bottom one might not be copper, scuff at it and see if it's copper all the way, might just be aluminium wire
