Typical Use

This Alloy Has All The Characteristics Of CuNi 90/10, But Also Offers Excellent Corrosion
Resistance In High Velocity Sea Water. Also The Operating Temperature Is Much Higher Than
Of CuNi 90/10. Can Assure A Long Service Life And Reliability.
Melting Point: 1240°C • Hot Working Properties: Good
Density (20°C): 8,94 G/Cm3 • Cold Working Properties: Good
Weight Formula Average Wall: (OD-WT) X WT X 0,0284 = Kg/M (All Sizes In Mm)
Minimum Wall: (OD-WT) X WT X 0,0295 = Kg/M (All Sizes In Mm)
Application range: Copper-Nickel Alloy tube for condenser and heat-exchangers, Water Evaporators, Boiler Blowdown Heat Exchangers, air coolers, Gland Steam Condensers, Steam Ejector, Turbine Oil Coolers, Fuel Oil Heaters, Compressed Air Inter and After Coolers, Ferrules, Oil Well Pump Liner, and Distiller etc.
