8.4g/Cm3 Density Copper Based Alloys Precision Resistance Wire CuNi43 / 6J13
(Common Name: Manganin 43,CuMn12Ni4,Manganin )
Shunt Manganin 43 is a copper-manganese-nickel alloy (CuMnNi alloy) for use at room temperature. The alloy is characterized by very low thermal electromotive force (emf) compared to copper.
Shunt Manganin43 widely used for Shunt resistor with the highest requirements, shunt manganin43 has been used in precision built electrical components such as Wheatstone bridges, decade boxes, voltage drivers, potentiometers and resistance standards.
