Copper Nickel fasteners are widely used in industries that demand high resistance to corrosion, extreme temperatures, and mechanical stress. These fasteners, made from copper-nickel alloys, provide outstanding durability and performance in marine, chemical, and power industries.

What Are Copper Nickel Fasteners?

Copper Nickel fasteners include various components such as bolts, nuts, washers, screws, and studs, manufactured from Cu-Ni 90/10 (90% copper, 10% nickel) and Cu-Ni 70/30 (70% copper, 30% nickel) alloys. These alloys are known for their superior resistance to seawater corrosion, biofouling, and thermal conductivity.

Key Features of Copper Nickel Fasteners

• High Corrosion Resistance – Ideal for marine and chemical environments.

• Excellent Mechanical Strength – Ensures durability in high-stress applications.

• Thermal Stability – Performs well in extreme temperatures.

• Anti-Fouling Properties – Prevents marine growth on submerged structures.

• Good Weldability and Ductility – Easy to fabricate and install.

• Non-Magnetic Nature – Suitable for sensitive applications.
