Product Description Copper nickel manganin resistance strip for Resistor 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 typically86%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.Chemical Content, %NiMnFeSiCuOtherROHS DirectiveCdPbHgCr2~511~13<0.5microBal-NDNDNDNDMechanical PropertiesMax Continuous Service Temp0-100oCResisivity at 20oC0.44±0.04ohm mm2/mDensity8.4 g/cm3Thermal Conductivity40 KJ/m·h·oCTemp Coefficient of Resistance at 20 oC0~40α×10-6/oCMelting Point1450oCTensile Strength(Hard)585 Mpa(min)Tensile Strength,N/mm2 Annealed,Soft390-535Elongation6~15%EMF vs Cu, μV/oC (0~100oC)2(max)Micrographic StructureausteniteMagnetic PropertynonHardness200-260HBMicrographic StructureFerriteMagnetic PropertyMagneticApplication of ManganinManganin 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.Temp Coefficient of Electrical Resistance(a×10-6/°C) 20°COperation Temperature°CResistivity(uΩ/m,20°C)EMF VS CuuV/°C(0~100°C)-0.7~400~1000.44±4%≤2Physical Characteristics (Reference Values)Density g/cm3Thermal conductivity(KJ/m.h°C)Tesile strength(N/mm2)SoftElongation%Tesile strength(N/mm2) Hard8.4 40390-5356~15≥585
