When corrosion resistance and long-term durability are critical, Copper-Nickel 90/10 Butt Weld Fittings are one of the most reliable solutions available. Manufactured from UNS C70600, this alloy is specially designed to perform in seawater, brackish water, and aggressive industrial environments.
We manufacture and supply premium-grade Cu-Ni 90/10 Buttweld Fittings for marine, offshore, power, and chemical industries. Our focus is not only on meeting standards but on delivering fittings that perform reliably in real working conditions.
What is UNS C70600 Copper-Nickel 90/10?
UNS C70600 (also known as Copper-Nickel 90/10 or Cu-Ni 90/10) contains approximately 90% copper and 10% nickel, with controlled additions of iron and manganese. These additional elements improve resistance to erosion and impingement corrosion, especially in flowing seawater systems.
Because of this balanced composition, Copper 90/10 Welded Fittings are widely used in:
- Shipbuilding and naval vessels
- Offshore oil & gas platforms
- Seawater cooling lines
- Desalination plants
- Power plant condensers
Unlike carbon steel, this alloy does not rust easily and maintains structural integrity for decades when properly installed.
Key Benefits of Copper-Nickel 90/10 Butt Weld Fittings
- Exceptional Seawater Corrosion Resistance: The alloy forms a natural protective layer that prevents rust and corrosion in marine environments.
- Resistance to Biofouling: Copper content naturally prevents marine organisms from attaching to pipe surfaces.
- Long Operational Life: Compared to coated carbon steel, Cu-Ni 90/10 Buttweld Fittings require minimal maintenance.
- Excellent Weldability: Perfect for shipyards and offshore fabrication where reliable welding is essential.
- High Thermal Conductivity: Ideal for condensers and heat exchanger systems.
