Manganin (CuMn12Ni4, grade 6J13, F2 manganin / Manganin 43) precision resistance alloy wire — the preferred grade for current shunts and sampling resistors.
Very low temperature coefficient of resistance (TCR) of ±(5–10)×10⁻⁶/°C, ensuring excellent resistance stability over temperature.
Resistivity 0.44±0.04 μΩ·m at 20°C; very low thermoelectric EMF vs copper (≤1 μV/°C) and outstanding long-term resistance stability.
Diameter range 0.05mm to 3.0mm, supplied on spools or coils; soft or hard temper available.
Ideal for DC/AC current shunts, energy meters, ammeters, precision sampling resistors, resistance standards and high-precision measuring instruments.
