Copper Nickel fasteners are a critical component in industries requiring high strength, excellent corrosion resistance, and long-term durability. Composed of copper and nickel, these fasteners are widely used in marine, chemical, and industrial applications where exposure to harsh environments is a concern.

What Are Copper Nickel Fasteners?

Copper Nickel fasteners are made from alloys containing a high percentage of copper with nickel as the primary alloying element. The most popular compositions are Cu-Ni 90/10 (90% copper, 10% nickel) and Cu-Ni 70/30 (70% copper, 30% nickel). These alloys offer superior resistance to corrosion, biofouling, and mechanical stress.

Properties of Copper Nickel Fasteners

• Corrosion Resistance: Exceptional resistance to seawater, acids, and chemicals.

• High Durability: Withstands high pressure, temperature variations, and harsh conditions.

• Excellent Ductility and Strength: Allows for easy installation and reliable fastening.

• Thermal and Electrical Conductivity: Ideal for heat exchangers and electrical systems.

• Non-Magnetic Properties: Suitable for sensitive industrial and marine applications.

Why Choose Copper Nickel Fasteners?

1. Resistance to Marine and Chemical Corrosion – Protects against rust and biofouling.

2. Long-Lasting Performance – Minimal maintenance with extended service life.

3. Compatibility with Various Materials – Prevents galvanic corrosion when used with different metals.

4. Cost-Effective Solution – Reduces repair and replacement costs over time.

5. Versatility in Applications – Used in shipbuilding, offshore platforms, and power plants.
