Copper Nickel 70/30 Fasteners are tough and reliable components made from an alloy that consists of 70% copper and 30% nickel, with a touch of iron and manganese added to boost their strength and resistance to corrosion. These fasteners are highly valued for their remarkable ability to resist seawater corrosion, stress corrosion cracking, and erosion, making them perfect for marine and offshore applications. They’re recognized for their durability, long lifespan, and dependability in harsh conditions. Copper Nickel 70/30 Fasteners provide secure and stable connections in critical systems, ensuring consistent performance with minimal upkeep.
The makeup of Copper Nickel 70/30 Fasteners features 70% copper and 30% nickel, along with carefully controlled amounts of iron and manganese to enhance their resistance to pitting and erosion. This alloy boasts excellent mechanical properties, including high tensile strength, ductility, and impressive toughness. The fasteners show remarkable resistance to biofouling and maintain their structural integrity even under high pressure and elevated temperatures. They’re also easy to weld and fabricate, making them ideal for complex assemblies. Their combination of mechanical strength and corrosion resistance makes them a reliable choice for demanding service conditions.
