    Got some cheap supposed cat5e (it may be to spec) the conductors appear
    to be copper plated aluminium, it seems to be fairly thick plating ,the
    pairs are well twisted.
    would there be any inherent problems with this cable? I can not see
    major problems unless the connections cut through the copper. The
    current carrying capabilities may differ as the conductors are supposed
    to be the same diameter as the copper. I assume the resistance may
    differ but would that matter significantly?

    Copper is the better conductor but aluminium is LIGHTER and CHEAPER
    hence the use in overhead town electricity wiring.

    The aluminium in outside electricity wiring may not be pure aluminium
    but may be alloyed to enhance particular features. The wiring around my
    town is doing alright long term however I see there is still a lot of
    copper left in the system. There have been major upgrades around here
    recently and all new is aluminium. I guess they make a packet out of
    scrap copper when they take the old lines down.

    I thought that aluminium was a better conductor than copper actually ?

    ** Copper is the better conductor for a given cross section.

    However, for the same weight of cable, aluminium has half the resistance.

    Both conductors lack strength, so cables strung between poles or towers have
    steel cores with copper or aluminium strands wrapped around.
