Copper-Nickel Tube: End Forming & Bending Services
Valued for its exceptional resistance to seawater corrosion and biofouling, copper-nickel is a trusted material for tube fabrication in applications where durability in wet, saline, and marine environments is essential. Its combination of corrosion resistance, antimicrobial properties, and structural reliability makes it a preferred choice for demanding fluid handling and offshore systems. When you need copper-nickel tube end forming or bending services, the experts at FormFab have you covered.
Copper-Nickel Tubing Properties
Copper-nickel, sometimes called cupronickel, is a family of copper-based alloys combined with nickel and other strengthening elements. Despite a high copper content, the material has a distinctive silvery appearance. Two alloy compositions are most commonly used for tube fabrication:
Two alloy compositions are most commonly used for tube fabrication:
- 90/10 Copper-Nickel: Offers solid corrosion resistance with high formability, suited for general marine and fluid handling applications
- 70/30 Copper-Nickel: Provides enhanced strength and corrosion resistance, preferred for applications with direct or prolonged seawater exposure
Key material characteristics include:
- Corrosion resistance in seawater and chemically aggressive environments
- Resistance to crevice corrosion and pitting
- Antimicrobial properties that inhibit bacterial growth on tube surfaces
- Low adhesion for marine organisms, limiting biofouling buildup
- Non-sparking behavior suitable for use in hazardous or sensitive environments
Applications of Copper-Nickel Tubing
Marine and industrial operations depend on copper-nickel in fluid handling systems that must perform reliably under corrosive conditions. Common applications include:
- Seawater intake systems
- Desalination processes
- Vessel conveyance lines
- Offshore oil and gas processing
- Power generation systems
