Product Description

Corrosion Resistant Cupro Nickel 70/30 Plate C71500 CuNi Sheet ASME SB171 Heat Exchanger


1. Product Description

Copper Nickel Plate is a low‑alloy copper‑nickel plate containing 10% or 30% nickel with controlled iron and manganese additions, specifically developed for high‑velocity seawater and marine atmospheric service. The alloy exhibits exceptional resistance to uniform corrosion, impingement attack, and crevice corrosion in chloride‑bearing environments. Principal designations are CuNi90/10 (UNS C70600) and CuNi70/30 (UNS C71500), along with Chinese grades BFe10‑1‑1 and BFe30‑1‑1. Plates are produced via hot rolling (HR) for thicknesses ≥5 mm, and cold rolling (CR) for thicknesses 0.4–4 mm. Delivery conditions include annealed (soft), 1/4 hard, 1/2 hard, and full hard. Surface finishes offered: HR pickled (ASTM #1), CR bright (ASTM #2B), polished (mirror or satin), and chequered (diamond, teardrop, or lentil). All products meet ASTM B171, ASME SB171, or GB/T 15272.


2. Product Applications

  • Ballast water exchange systems (sequential method): Flow distribution plates, venturi injector mounting plates.

  • Marine growth prevention systems (MGPS): Electrode plates for copper‑aluminum anodes, control panel enclosures.

  • Subsea cable protection: Bend stiffener connector plates, cable gland backing plates.

  • Shipboard LNG fuel systems: Seawater vaporizer plates for LNG warming, leak detection tray liners.

  • Tidal barrage gates: Gate wheel contact plates, seal support plates, trash rack bars.

  • Coastal defense radar towers: Cladding plates for corrosion protection in splash zone.

3.Product Advantages

  • Outstanding resistance to flow‑induced corrosion (FIC) in turbulent seawater – Proven in long‑term pipe loop tests.

  • Excellent resistance to ammonia and ammonium salt attack – Suitable for urea and fertilizer plant cooling systems.

  • High tensile strength retention at elevated temperatures – Retains 80% of room temperature tensile at 260°C.

  • Good impact toughness down to −269°C (liquid helium) – No ductile‑to‑brittle transition.

  • Easily sheared and punched without edge cracking – Cold workable even in half‑hard condition.

  • Readily available with NACE MR0175/ISO 15156 compliance – For sour service applications (limited H₂S).

  • Cost‑competitive with 6% molybdenum stainless steels – Lower raw material cost in many markets.
