90/10 Cupro Nickel Tubes
90/10 Cupro Nickel is a 90% Copper, 10% Nickel Alloy that also contains small but Important additions of Iron and Manganese to enhance overall Strength Corrosion Resistance. This, combined with High Ductility and Toughness, Makes it a Popular Grade for Marine, Architectural and industrial Applications.
90/10 Alloy offers Designers and Specifiers excellent resistance to Stress Corrosion, Erosion, and Biofouling in Sea Water and Brackish Water, Excellent Fabrication and Welding Properties, a High Resistance to Hydrogen embrittlement and the retention of Mechanical Properties down to Cryogenic Temperatures.
Product Application Areas:
Chillers, Heat Exchange & Condensers , Power Plants, Refineries , Desalination Plants, Ship Building & Ship Repairs, Defense.
