High Quality Cr20ni30 Alloy Resistance Wire - China

price: 22.00 Dollar US$

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.

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.
