ultrapure copper magnet wire?

[Fred_Bartoli]

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.
