Copper Nickel 90/10 fasteners are crafted from an alloy that consists of about 90% copper and 10% nickel, with a touch of iron and manganese to boost strength and corrosion resistance. This alloy is celebrated for its remarkable ability to resist saltwater corrosion, biofouling, and stress corrosion cracking. The mechanical properties are impressive, featuring a tensile strength of 275–350 MPa, a yield strength of around 120 MPa, and an elongation of about 30%. These fasteners hold their structural integrity even under high pressure and temperature, making them perfect for a variety of marine and industrial applications.

In the marine and shipbuilding sectors, Copper Nickel 90/10 fasteners are a go-to choice thanks to their exceptional resistance to seawater corrosion and marine biofouling. They’re commonly found in seawater piping systems, heat exchangers, pumps, valves, and other components that face harsh conditions. Additionally, these fasteners are utilized in desalination plants, offshore oil and gas operations, and power generation facilities. Their durability, low maintenance needs, and ability to endure aggressive fluids make them an ideal option for critical fastening in corrosive and high-performance environments.
