Shunt Manganin 43 Precision Resistance Wire 6j13 for Shunt Resistor
Shunt Manganin 43(Precision Resistance wire)
(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.

Application of Manganin
Manganin 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.
The copper-based low resistance heating alloy is widely used in low-voltage circuit breaker, thermal overload relay, and other low-voltage electrical product. It is one of the key materials of the low-voltage electrical products. The materials produced by our company have the characteristics of good resistance consistency and superior stability. We can supply all kinds of round wire, flat and sheet materials.
Copper nickel alloy series:Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44.
