Product Description

Factory Direct Sales Constantan CuNi44 Copper-Nickel Alloy Wire

Constantan Wire for Sampling Resistor is a copper-nickel alloy usually consisting of 55% Copper and 45% Nickel. Its main feature is its resistance which is constant over a wide range of temperatures. It is also called Alloy 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 44, CuNi 44, CN49.

Regular size:  

We supply products in the shape of wire,flat wire,strip.We can also make customized material according to useris requests.

Bright and white wire--0..03mm~3mm

Oxidized wire:0.6mm~10mm

Flat wire:thickness 0.05mm~1.0mm,width 0.5mm~5.0mm

Strip:0.05mm~4.0mm,width 0.5mm~200mm

Product features:

Nice corrosion resistance, good malleability and solderability.The special low resistance can be used in many heater and resistor fields.

 

Application:

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.And used in heat exchanger or condenser tubes in evaporators of desalination plants, process industry plants, air cooling zones of thermal power plants, high-pressure feed water heaters, and sea water piping in ships.
