Copper Nickel Fasteners are crafted from a blend of copper and nickel, typically in grades like 90/10 and 70/30, with minor additions of iron and manganese to boost strength. This unique composition grants them outstanding resistance to seawater corrosion and stress corrosion cracking. On the mechanical side, Copper Nickel Fasteners exhibit impressive tensile and yield strength, along with excellent ductility and toughness. They remain stable even at high temperatures, possess low magnetic permeability, and provide dependable performance under continuous load, vibration, and challenging environmental conditions, ensuring secure and long-lasting fastening solutions.
