Product Description

Karma alloy is made up of Copper,Nickel,Aluminum,Iron as the main components.
The resistivity is2-3 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 elemengts and strain.
