Cupro Nickel 90/10 Tubes – Supplier, Stockist
and Exporter in Mumbai, India

Cupro Nickel 90/10 (UNS C70600) Tubes to ASTM B111

90/10 cupro-nickel (UNS C70600, DIN 2.0872, CuNi10Fe1Mn) contains about 90% copper and 10% nickel, with small additions of iron (1.0–1.8%) and manganese. The iron addition gives it excellent resistance to seawater corrosion and erosion.

Properties and Uses of Cupro Nickel 90/10 Tubes

90/10 cupro-nickel combines excellent seawater corrosion resistance with natural resistance to biofouling, good resistance to stress-corrosion cracking, and easy fabrication and welding.

Where not to use it: Avoid sulphide-polluted water and very high flow velocities (above about 3.5 m/s in pipework). For higher velocities choose 70/30 cupro-nickel.

Testing, Documentation and Packaging

Every lot of Cupro Nickel 90/10 tubes is inspected before dispatch. Typical tests include chemical analysis / PMI, tensile and hardness testing, flaring and flattening tests, hydrostatic or eddy-current testing, and dimensional inspection. 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 wrapped in poly bags and packed in fumigated wooden cases, crates or pallets, with a fumigation certificate included.
