Copper Alloy Manganin Wire 6j8 Copper-Nickel Alloys
Model No.: 6J8
Very good malleability
Very good solderability
For the manufacturing of low temperatures electric resistances so as heating principally destined cables, shunts, resistances for automobile, they have a maximum operating temperature of 400 ° C.
They do not therefore intervene in the field of resistances for industrial furnaces.
Those are alloys of chemical composition copper + nickel with addition of manganese with a low resistivity (from 0.49 to 0.05 Ohm mm² /m).
The most known, CuNi 44 (also called Constantan) presents the advantage of a very low temperature coefficient.
|Characteristic||Resistivity ( 200C μΩ.m)||Max.working Temperature ( 0C)||Tensile Strength (Mpa)||Melting point (0C)||Density ( g/cm3)||TCR x10-6/ 0C (20~600 0C)||EMF vs Cu (μV/ 0C) (0~100 0C)|
