Copper Nickel 95/5 Tubes Manufacturer

Copper Nickel 95/5 Tubes, also known as Cupro Nickel 95/5 Tubes or UNS C70400 Tubes, are copper-nickel alloy tubes containing approximately 95% copper and 5% nickel with small additions of iron and manganese. These tubes offer excellent resistance to seawater corrosion, biofouling, erosion, and chloride attack, making them ideal for condensers, heat exchangers, desalination plants, offshore platforms, marine piping, and power generation systems. Available in seamless, welded, capillary, condenser, and U bent tube configurations, they provide long service life with minimal maintenance.

Detailed Information

Copper Nickel 95/5 Tubes Supplier

We supply premium-quality Copper Nickel 95/5 Tubes manufactured to international standards for demanding industrial environments. Our product range includes Cu-Ni 95/5 Tubing, UNS C70400 Tubes, Copper Nickel 95/5 Seamless Tube, Cupro Nickel 95/5 Condenser Tubes, Copper Nickel 95/5 Heat Exchanger Tubes, Copper Nickel 95/5 U Bent Tubes, and C70400 Capillary Tubing for industries requiring outstanding corrosion resistance and reliable performance.

The Copper Nickel 95/5 alloy is widely recognized for its exceptional resistance to seawater, brackish water, and industrial cooling systems. The addition of nickel improves strength and corrosion resistance while maintaining the excellent thermal conductivity of copper. This makes UNS C70400 Tubes a preferred solution for condensers, heat exchangers, hydraulic systems, marine piping, and desalination plants.

As experienced Cupro Nickel 95/5 Pipe Suppliers and UNS C70400 Seamless Tube Stockist, we supply tubes in various sizes, wall thicknesses, lengths, and finishes to meet project-specific requirements. Every tube undergoes strict quality inspections, dimensional verification, and testing before dispatch to ensure dependable performance.
