Product Description

Product Description

Evanohm alloy is made up of copper, nickel, Aluminum and chromium 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 antioxidation. Its working temperature range is wider than manganin (-60~300ºC). 
It is suitable for making fine precision resistance elements and strain.
