Karma is made up of chrome nickel, Alumium and Iron as the main components.The resistivity is 2~3 times higher thanmanganin.
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.
The Nickel-Chrome and Nickel-Chrome-Iron alloy wires are widely used as the high resistance alloy for electrical heating and wire-wound resistors in metallurgical industry,chemical industry and electrical industry, etc.
This alloy wire has higher electrical resistance coefficient, good anti-oxidation and anti-corrosion performance, and it also has good mechanical workability and weldability, with a high strength at high temperature.
