Copper nickel 70 30 thermal conductivity is 29 W/(m·K). The Elongation at Break of Copper nickel (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. The Density of 70/30 Copper nickel is 0.323 lb/in³ (8.94 g/cm3). Cupro Nickel 70/30 contains 70% copper and 30% nickel. It also has a small amount of manganese and iron in it, making it more resistant to erosion and corrosion. The resistance of 70/30 CuNi has been found to be much better in polluted seawater and in high-velocity waters (up to 4.5m/s).
