Cupro Nickel 90/10 Fasteners
Cupro-Nickel 90/10 Fasteners are hardware components made from an alloy known as Copper-Nickel 90/10, also referred to as C70600. This alloy is a combination of 90% copper and 10% nickel, along with trace amounts of other elements such as iron and manganese. The composition of Cupro-Nickel 90/10 provides a unique balance of properties that make it ideal for various engineering applications.
One of the key features of Cupro-Nickel 90/10 Fasteners is their excellent resistance to seawater corrosion and biofouling. This alloy is widely used in marine environments, as it offers exceptional resistance to marine organisms and chloride-induced corrosion. Cupro-Nickel 90/10 Fasteners are resistant to crevice corrosion, stress corrosion cracking, and erosion, making them suitable for applications in shipbuilding, offshore structures, and desalination plants.
