Home > Copper Nickel > Copper Nickel 70/30 Fittings
Copper Nickel 70/30 fittings are top-notch piping components crafted from a blend of 70% copper and 30% nickel. These fittings shine when it comes to resisting corrosion, especially in seawater and other harsh environments, all while boasting impressive mechanical strength and durability. They stand up well against biofouling, erosion, and stress corrosion cracking, making them perfect for marine, offshore, and industrial piping systems that need to last.
Typically, the makeup of Copper Nickel 70/30 fittings includes 70% copper and 30% nickel, along with a dash of iron and manganese to boost their strength and corrosion resistance. They deliver solid tensile strength, toughness, and ductility, which means they can handle high-pressure and high-temperature situations with ease.
