Copper Nickel 70/30 tubing is a top-notch alloy made up of 70% copper and 30% nickel. This unique blend gives it fantastic resistance to corrosion, especially in seawater and other harsh environments, all while keeping solid thermal and electrical conductivity. Its strength against biofouling and erosion makes it a perfect choice for marine, offshore, and industrial uses where long-lasting reliability is a must.
Typically, Copper Nickel 70/30 tubing consists of 70% copper, 30% nickel, along with small amounts of iron and manganese to boost its strength and corrosion resistance. It boasts impressive tensile strength, ductility, and flexibility for easy fabrication, and it can handle high pressures and temperatures without breaking down significantly.
