CuMn12Ni2 Manganin wire rod precision manganin wire

CuMn12Ni2 Manganin wire rod precision manganin wire
Product Description
Manganin wire widely used forlowvoltage instrumentationwith the highest requirements, the resistors should be carefully stabilised and the application temperature should not exceed +60 °C. Exceeding the maximum working temperature in air may result in a resistance drift generated by oxidizing. Thus, the long-term stability can be affected negatively. As a result, the resistivity as well as the temperature coefficient of the electric resistance may slightly change. It is also used as low cost replacement material for silver solder for hard metal mounting.
