Product Description
Cold Rolled CuNi 70/30 Plate C71500 ASTM B171 Copper Nickel Alloy Sheet for Condenser
1. Product Description
Copper Nickel Plate is a copper‑nickel‑iron‑manganese alloy plate engineered for long‑term service in seawater, brine, and industrial cooling water systems. The alloy provides excellent resistance to general corrosion, erosion‑corrosion, and crevice attack. Key grades are CuNi90/10 (UNS C70600) and CuNi70/30 (UNS C71500), with Chinese equivalents BFe10‑1‑1 and BFe30‑1‑1. Production processes include hot rolling (HR) for plates thicker than 4 mm and cold rolling (CR) for plates down to 0.4 mm. Heat treatment (solution annealing) is applied to achieve optimal corrosion resistance and ductility. Surface conditions include hot rolled and pickled, cold rolled bright (2B), polished to various grits, and chequered patterns (diamond, lentil, or teardrop). All products are certified to ASTM B171, ASME SB171, EN 1652, or GB/T 15272.

2. Product Applications
-
Steam surface condensers (power plants): Tube support plates (baffles), waterbox linings, impingement protection plates.
-
FPSO topside modules: Seawater injection filter housings, chemical injection skid plates, deck drain sump covers.
-
Marine diesel engines: Freshwater cooler plates for jacket water cooling, seawater charge air cooler plates.
-
Subsea production systems: Jumper support plates, subsea distribution unit baseplates, ROV interface plates.
-
Coastal sewage treatment: Outfall diffuser plates, screening tank baffles, aeration tank covers.
-
Specialty chemical storage: Tank bottom plates for dilute acetic acid and phosphoric acid service.
3.Product Advantages
-
Superior resistance to impingement attack in turbulent flow – Verified by jet‑impingement tests (ASTM G78).
-
Excellent resistance to sulphide stress corrosion cracking (SSCC) – Suitable for environments with up to 50 ppm H₂S.
-
Good resistance to galling and seizing – Used for threaded connections and sliding contact surfaces.
-
Readily bendable with simple tooling – Air bend or bottom bend without requiring special die materials.
-
High electrical resistivity compared to pure copper – Useful for applications requiring moderate resistance (e.g., resistor plates).
-
Non‑sparking and non‑magnetic – Safe for hazardous areas and mine countermeasure vessels.
-
Global supply chain with short lead times – Stocking locations in Asia, Europe, and North America.
