6j13/6j8/6j12 copper-manganese-nickel alloy for Manganin shunt

The precision resistance alloy MANGANIN is especially characterized by low temperature coefficient between 20 and 50 °C with a parabolic shape of the R(T) curve, high long term stability of electrical resistance, extremely low thermal EMF versus copper and good working properties.
However, higher thermal loads in a non-oxidizing atmosphere are possible. When used for precision resistors with the highest requirements, the resistors should be carefully stabilised and the application temperature should not exceed 60°C. Exceeding the maximum working temperature in air may result in a resistance drift generated by oxidizing processes.Thus, the long term stability can be affected negatively. As a result, the resistivity as well as the temperature coefficient of the electric resistance may slightly change. It is also used as low cost replacement material for silver solder for hard metal mounting.

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.
