Hakan Nickel Alloys, based in Istanbul, Turkey, is a reputable manufacturer and supplier of top-notch metal fasteners, including Copper Nickel Bolts. Renowned for their precision engineering and reliable performance, the company provides fastening solutions for challenging marine, offshore, industrial, and power generation environments. Their Copper Nickel Bolts are crafted to endure corrosive conditions, high temperatures, and mechanical stress, ensuring long-lasting reliability. Adhering to international standards, Hakan Nickel Alloys offers both standard and custom specifications, delivering bolts that guarantee strength, resistance, and an extended service life, even in the toughest operating conditions.
Typically made from 90/10 or 70/30 copper-nickel alloys, Copper Nickel Bolts blend corrosion resistance with impressive mechanical strength. These bolts boast tensile strengths ranging from 300 to 500 MPa and maintain their structural integrity under stress and vibration. The copper-nickel alloy effectively resists seawater corrosion, erosion, and stress cracking, while also being non-magnetic and thermally stable. Additionally, Copper Nickel Bolts are highly resistant to biofouling and hydrogen embrittlement. They are easy to machine, weld, and install, making them perfect for critical fastener applications where reliability, durability, and compatibility with other copper-nickel components are crucial.

Copper Nickel Bolts find extensive use in marine construction, shipbuilding, offshore platforms, and seawater systems, where standard fasteners might corrode or fail. They are particularly suited for securing flanges, valves, pumps, and structural components that are exposed to saltwater or chemical media. In power plants and desalination facilities, these bolts ensure dependable connections even under high temperatures.
