We can also offer CuNi44 in the form of wire,strip,if you have inquirements,please let me know.
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.
