Product Description

Constantan electric heating strip 6j40

Constantan  with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". Constantan also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits.

It could be used to make electric heating element in low-voltage apparatus, such as thermal overload relay, low-voltage circuit breaker, and so on.

Our company produce alloy foil, metal foil, steel foil thickness 0.005mm-0.1mm(5um-100um), width 1mm-1330mm.
