Need help identifying wire

[dizz1]

Greetings all!!!
Curious if anyone has any knowledge of this wire.
I did my version of research(lol) and came up with a special cable used at a local Air Force Base(Wright-Patterson).
Any help would be greatly appreciated and thanks in advance!

That's a copper-constantan thermocouple wire. Google it for more info.
You can use it as an extension wire for an existing Cu-Constantan thermocouple probe/sensor, or you can weld the tips together to make such a sensor/junction.

Constantan is used to make resistors also.

Resistor from constantan

Constantan is used to make resistors also.

Would you basically just coil it to the resistance you need?

If it's thermocouple wire, look it up for applications.
You've got more than you sound like you'll ever need.
Save some to play with if you want, and you'll get good money for selling the rest of
the roll.
Thermocouple wire is used extensively in zillions of industrial applications.

You can wind it any way you want, but realize a winding like a helical winding (like winding a single layer choke) may have substantial inductance. If you want to reduce the inductance, double the wire back on itself, then wind the helix. I've found from experiments that the inductance will be reduced by a factor of about 10. Or, look up things like a Ayrton-Perry winding.

Resistors generate heat, so if you want to make a high power resistor, you will need to strip the insulation. Measure the resistance of say one meter and calculate the length you need. If it is going to get hot, it will need to be wound on an insulating, high temperature former.
