Copper Nickel Fasteners mainly consist of copper, with carefully controlled amounts of nickel, along with trace elements of iron and manganese to boost strength and corrosion resistance. This alloy is known for its impressive resistance to seawater corrosion, stress corrosion cracking, and erosion. In terms of mechanical properties, these fasteners provide good tensile strength, excellent toughness, and stable performance even at high temperatures. They exhibit low macro-fouling characteristics and maintain their shape in both hot and cold marine conditions. Their well-balanced composition ensures reliable mechanical resilience, making them ideal for challenging coastal, industrial, and offshore environments.
