Copper Nickel Buttweld Fittings offer a good balance between corrosion resistance, affordability, and workability compared to other options like stainless steel.
They are commonly used in marine environments, seawater systems, desalination plants, and applications involving acidic or caustic fluids.
The grade selection (90/10 or 70/30) depends on the specific requirements of your project. Here’s a general guideline:
Copper Nickel 90/10 (Cu-Ni 90/10): Provides superior corrosion resistance, ideal for harsh environments like seawater.
Copper Nickel 70/30 (Cu-Ni 70/30): Offers a more economical option with good corrosion resistance, suitable for less severe applications.
Remember to consult with a specialist or engineer to determine the most suitable grade and specifications for your specific application.
