Cupro Nickel Sheets & Plates to ASTM B122
Cupro-nickel (copper-nickel) alloys combine copper with 5–30% nickel plus small iron and manganese additions. The two most widely used grades are 90/10 cupro-nickel (UNS C70600) and 70/30 cupro-nickel (UNS C71500), with 95/5 (UNS C70400) as a lower-cost option.

Properties and Uses of Cupro Nickel Sheets & Plates
Cupro-nickel alloys have excellent resistance to seawater corrosion and biofouling, good resistance to stress-corrosion cracking, and are easy to fabricate and weld.
Where not to use it: Avoid sulphide-polluted water. For high-velocity seawater, choose 70/30 cupro-nickel over 90/10.
Testing, Documentation and Packaging
Every lot of Cupro Nickel sheets & plates is inspected before dispatch. Typical tests include chemical analysis / PMI, tensile and hardness testing, bend testing, ultrasonic testing of plates where required, and checks of thickness and flatness. Third-party inspection can be arranged on request.
Material is supplied with a mill test certificate to EN 10204 3.1, together with the raw-material report and inspection reports. For export orders it is interleaved with protective paper and packed on fumigated wooden pallets or in wooden cases, with a fumigation certificate included.
