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.
sometimes cupro-nickels, there exists a range of different cooper nickel alloys that possess different properties and hence are suited to a range of different applications.
