Copper Nickel 70/30 Tube Fittings consist of 70% Copper and 30% Nickel, along with Iron (0.4–1.0%) and Manganese (0.5–1.0%) for improving strength and resistance against corrosion. These fittings possess tensile strength of approximately 380 MPa, yield strength of about 150 MPa, and elongation of roughly 30%. Density is 8.9 g/cm³ and melting range is 1170°C–1240°C. They exhibit superior resistance against seawater corrosion, erosion, and stress corrosion cracking, having good thermal but moderate electrical conductivity (~7% IACS). They are ideal for high temperature and high-pressure applications.
