Copper Nickel 70/30 Tube Fittings are incredibly dependable components designed for top-notch performance in marine, industrial, and offshore settings. Made up of 70% copper and 30% nickel, these fittings also include small amounts of iron and manganese to boost their strength and resistance to corrosion. They’re well-known for their impressive ability to withstand seawater, biofouling, and stress corrosion cracking, making them a go-to choice for durability and longevity. Their unique blend of strength, thermal stability, and weldability makes them perfect for demanding fluid handling systems where safety and reliability are absolutely essential.
With a composition of 70% copper and 30% nickel, these fittings offer remarkable resistance to corrosion in both saltwater and brackish conditions. The added iron and manganese enhance their mechanical strength and improve their resistance to erosion and pitting. Thanks to their good ductility, toughness, and weldability, Copper Nickel 70/30 Tube Fittings maintain their structural integrity even under high temperatures and pressures. Their outstanding mechanical properties make them ideal for both static and dynamic marine environments, ensuring leak-free performance and minimizing maintenance needs.
