2020 High quality 200 Alloy - Nicr20alsi Wire/Karma /6J22Wire for Resistors – TANKII Detail:
NiCr20AlSi wire/Karma/6j22 wire for Resistors
Karma alloy is made up of copper, nickel, Aluminum and Iron as the main components. The resistivity is 2~3 times higher than Manganin. 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 Manganin (-60~300ºC). It is suitable for making fine precision resistance elements and strain foil.
