Manganin Wire for Precision Instrument

Model NO.: 6J12 Material: Cu Ni Mn Trademark: TANKII Origin: China Product Type: Wire Carbon Content: No Specification: SGS HS Code: 74082900 Manganin Wire for Precision Instrument

Product Description
Manganin wire widely used for precision resistors with 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.
