Specifications:
1. Brief introduce of constantan (CuNi40/6J40) wire :
Constantan is a type of resistance alloy, which is made up of copper and nickel as the main components.It has a low temperature coefficient of resistance (TCR), and a wide operating temperature range (below 500°C). It has good properities on mechanical working, high resistance of corrosion. It is used for variable and strain resistance of corrosion. It is used for variable and strain resisitance elements in alternative instruments.
Constantan wire is CuNi40(6J40) wire Ni:39-41 Mn:1-2 Cu:rest
We can supply type of : wire,ribbon,strip, furnance spring wire
We can supply Size: Wire: 0.018mm-10mm
Ribbon: 0.05*0.2mm-2.0*6.0mm
Strip: 0.5*5.0mm-5.0*250mm
furnance spring wire according to customers requirement
2.Feature of constantan (CuNi40/6J40) wire
(1) High resistance
(2) Low temperature coefficient of resistance
(3) High working temperature
(4) Good corrosion resistance especailly under high temperature
