Product Description
6J12 Manganin Enameled Wire (CuMn12Ni2)
6J12 is a precision manganese copper nickel resistance alloy (CuMn12Ni2), widely known as Manganin. It combines a medium resistivity with an exceptionally low temperature coefficient of resistance and a low thermal EMF against copper, making it the preferred material for precision resistors, shunts and measuring instruments. This product is supplied as enamel coated wire, with a durable insulating enamel layer that allows tight winding and reliable electrical isolation.
1. Key Features
- Near zero temperature coefficient of resistance for high precision resistors
- Low thermal EMF against copper for accurate current measurement
- Medium and stable resistivity with long term stability
- Durable enamel insulation suitable for tight winding and compact coils
- Excellent corrosion resistance and good workability
2. Applications
- Precision resistors, standard resistors and potentiometers
- Shunts for ammeters and current sensing
- Measuring and calibration instruments
- Electronic loads and precision control equipment
