annealed manganin wire for Shunt /Resistor /6J13
Manganin wire is a trademarked name for an alloy of typically 86%copper,12%manganese, and 2%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.
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.
