Konstantan (Constantan) Resistance Alloy
Konstantan is copper nickel electrical resistance alloy. Pure copper adds nickel which can increase strength, corrosion resistance, hardness, electric resistance and thermal electricity, and decrease electrical resistance temperature coefficient.
With low electrical resistance temperature coefficient, wider temmperature(<480℃), good workability and weldability. Besides Konstantn resistance alloy, we still have New Konstantan resistance alloy which is copper iron based alloy, their parameters are same. Compared with Konstantan, new Konstantan is cheaper, but oxidation resistance is worse than Konstantan.
