I search for Nichrome plate long time, and successfully bought it from Ohmalloy material. OHMALLOY provide real good service in alloy service and can always help me in finding the correct resistance alloy.

—— Mike Harness

OHMALLOY can provie me only 1kg Kovar alloy wire 1.0mm with short time, that is really amazing. Thanks

—— Janey

Really professional in thermocouple wire and cable, what i want just can get from OHMALLOY

—— Chris

Enamelled Constantan 0.08mm, i never expect to get only 2kg of it. But OHMALLOY supply it to me with good quality. God Jesus! Such a reliable supplier from china

Resistance Rheostat CuNi6 CuNi8 CuNi10 CuNi14 Wire Long Useful Life

 

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
