6J22 Flat Wire With Superior Mechanical Properties For Strain Gauges And Sensor Components

Short Description:

Karma alloy is made up of copper, nickel, Aluminum and Iron as the main components. The resistivity is 2~3 times higher than MENTONG.
It has lower temperature coefficient of resistance(TCR), lower thermal EMF versus copper, good permanence of resistance for a long period of time
and strong anti-oxidation. Its working temperature range is wider than MENTONG (-60~300ºC). It is suitable for making fine precision resistance elements and strain.
