Copper Nickel Fasteners – Durable & Corrosion-Resistant for Marine & Industrial Use
Copper Nickel Fasteners are widely recognized for their superior corrosion resistance, durability, and strength, making them the go-to choice for demanding environments such as marine, offshore, chemical, power generation, and desalination industries. With the ability to withstand saltwater, extreme temperatures, and aggressive chemicals, these fasteners deliver unmatched reliability and long service life.
Types of Copper Nickel Fasteners
At AstroForge Fitting Industries, we manufacture and supply a complete range of copper nickel fasteners designed for diverse applications:
♦ Bolts, Stud Bolts, Hex Head Bolts, Socket Head Screws
♦ Anchor Bolts, U-Bolts, J-Bolts, T-Head Bolts
♦ Mushroom Head Square Neck Bolts, Wing Screws, Nuts, and Washers
Available in metric sizes (M3–M56) and inch sizes (3/6″–2″), our fasteners ensure compatibility across international projects.
Grades of Copper Nickel Fasteners
We provide copper nickel fasteners in two primary grades:
♦ Copper Nickel 90/10 (C70600): With 90% copper and 10% nickel, this alloy offers excellent seawater and erosion resistance. Commonly used in shipbuilding, offshore rigs, and desalination plants.
♦ Copper Nickel 70/30 (C71500): Containing 70% copper and 30% nickel, this alloy provides enhanced strength, durability, and resistance to biofouling, making it ideal for power plants, heat exchangers, and chemical processing industries.
Key Benefits of Copper Nickel Fasteners
♦ Exceptional Corrosion Resistance: Withstand harsh marine and industrial conditions.
♦ Durability & Strength: High performance even in extreme pressures and temperatures.
♦ Resistance to Biofouling: Prevents marine growth and oxidation.
♦ Long Service Life: Reduces downtime and maintenance costs.
♦ Versatile Applications: Suitable for multiple industries worldwide.
