Product Description Ultra-thin Eureka/Constantan/CuNi40/CuNi44/ Resistance Foil for Etching resistanceConstantan DefinitionResistance alloy with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". CuNi44 Alloy wire also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Wire is also the negative element of the type J thermocouple with Iron being the positive; type J thermocouples are used in heat treating applications. Also, it is the negative element of the type T thermocouple with OFHC Copper the positive; type T thermocouples are used at cryogenic temperatures.Chemical Content(%) CuNi44 NiMnFeSiCuOtherROHS DirectiveCdPbHgCr441.50%0.5-Bal-NDNDNDND Mechanical Properties CuNi44 Max Continuous Service Temp400 oCResistivity at 20oC0.49 ± 5% ohm*mm2/mDensity8.9 g/cm3Temperature Coefficient of Resistance< -6 ×10-6/oCEMF VS Cu (0~100oC)-43 μV/oCMelting Point1280 oCTensile StrengthMin 420 MpaElongationMin 25%Micrographic StructureAusteniteMagnetic PropertyNon.Product features:1)Excellent anti-oxidation and mechanical strength at high temperature;2)High resistivity and low temperature coefficient of resistance;3)Excellent reelability and forming performance;4)Excellent welding performace
