Normal Manganin low Resistance Strip

Common Name:Normal Manganin,Normal Manganin 47,CuMn12Ni2,6J12
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.

    Manganin is also used in gauges for studies of high-pressure shock waves (such as those generated from the detonation of explosives) because it has low srtain sensitivity but high hydrostatic presssure sensitivity.
