ultrapure copper magnet wire?

    we're seeking for high purity (6n-7n?) magnet wire. Preferably of the self
    bonding variety.

    Anyone knowing where I can source that?

    (no that's not for rewiring a toobs amp :)

    I certainly don't, but that kind of purity is probably only found in
    better temperature standards; such as a copper freeze point unit.

    OK, maybe not 6n. But definitely better than the garden variety magnet wire.

    We've got trouble with magnetic impurities in a ***sensitive*** magnetic
    sensor.
    (even the coil former platics gave us problems).

    www.goodfellow.com lists copper wire 99.99+% pure, and they have various
    polyurethane and polyimide insulations available, too. Give them a call and
    see what they recommend; this kind of material sourcing stuff is what they
    do.

    How clean do you want? OFHC is usually quite good from a magnetics
    point of view. The next problem is getting it coated without it
    picking up magnetic materials in the process.

    BTW: Where in the world are you?

    I don't know about magnet wire but a recent google revealed some sources for
    at least 6n Cu.
