Specifications
manganin wire/CuMn12Ni2 Wire used in rheostats, resistors,shunt etc manganin wire 0.08mm to 10mm 6J13, 6J12, 6J11 6J8
Manganin wire( cupro-manganese wire ) is a trademarked name for an alloy of typically 86%copper,12%manganese, and 2-5%nickel .
Manganin wire and foil is used in the manufactue of resistor,particularly ammeter shunts ,because of its cirtually zero temperature cofficient of resintance value and long terms stability.

Application of Manganin
Manganin foil and wire is used in the manufacture of resistor, Particularly ammeter shunt, because of its virtually zero temperature coefficient of resistance value and long term stability.
The copper-based low resistance heating alloy is widely used in low-voltage circuit breaker, thermal overload relay, and other low-voltage electrical product. It is one of the key materials of the low-voltage electrical products. The materials produced by our company have the characteristics of good resistance consistency and superior stability. We can supply all kinds of round wire, flat and sheet materials.
