Product Description
Karma wire size: 0.018-5.0mm
We use vaccum furmance melting chrome, nickel, Aluminum and Iron as the main components, hydrogen annealing and continuous wire drawing products line to produce karma alloy wire.  Our special inspection equipment is utilized to ensure the tensil strength, resistance and electromotie force the karma wire are up to par.
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 (-60~300º C). It is suitable for making fine precision resistance elements and strain.

As a big manufacturer and exporter in China on the line of electric heating Alloy, we can supply all kinds of the electric heating wire and strips (resistance steel wire and strips).

Hope you can enjoy of total quality and best service.
