Product Description
ASME SB171 CuNi 70/30 Copper Nickel Plate C71500 Anti-Corrosion Sheet
1. Product Description
Copper Nickel Plate is a corrosion‑resistant copper‑nickel alloy plate used extensively in seawater, brackish water, and freshwater systems. The alloy combines copper with nickel (typically 10% or 30%) plus iron and manganese to provide improved strength and resistance to flow‑induced corrosion. Common designations include UNS C70600 (CuNi90/10) and UNS C71500 (CuNi70/30), plus Chinese grades BFe10‑1‑1 and BFe30‑1‑1. These plates are produced by hot rolling with subsequent annealing and pickling. Cold rolling can be applied to achieve precise dimensional tolerances and improved surface smoothness. The plates are available in a variety of thicknesses, widths, lengths, tempers (soft, half‑hard, hard), and surface finishes (mill, pickled, 2B bright, polished, chequered). All products comply with ASTM B171, ASME SB171, or GB/T 15272 standards.
2. Product Applications
Seawater intake systems: Trash rack bars, traveling screen panels, intake pipe liners.
Marine propulsion: Adjustable pitch propeller blades (small craft), water jet pump housings.
Offshore wind farms: Transition piece sheathing, cable protection tubes (J‑tubes), corrosion protection plates on monopiles.
Shipboard systems: Distilling plant heat exchanger plates, boiler feed water preheaters.
Industrial heat transfer: Evaporator plates for crystallizers, condenser plates for petrochemical plants.
Architectural cladding: Coastal building facades, lighthouse exterior panels.
3.Product Advantages
Outstanding resistance to flow‑accelerated corrosion (FAC) – Retains protective film at velocities up to 3.5 m/s.
Excellent resistance to hydrogen cracking – Suitable for sour service (wet H₂S) environments within pH limits.
Good thermal conductivity compared to stainless steels – Higher heat transfer coefficient reduces required surface area.
Simple welding procedure – No need for post‑weld heat treatment; weld metal properties match base metal.
High resistance to ammonia attack – Suitable for environments with trace ammonia (e.g., urea plants).
Available with classification society certifications – ABS, DNV, LR, BV, CCS, NK can be provided with surcharge.
Easy to drill, punch, and shear – Reduces fabrication cost and lead time.
