Marine Grade CuNi 70/30 Copper Nickel Plate ASTM B171 C71500 Anti-Corrosion Sheet
1. Product Description
Copper Nickel Plate (Cupronickel Plate) is a high‑performance copper‑nickel alloy plate primarily used in marine, chemical, and power generation industries. The alloy combines copper with nickel (typically 10% or 30%) plus iron and manganese to enhance strength and corrosion resistance. Standard grades include UNS C70600 (90/10 CuNi), UNS C71500 (70/30 CuNi), and Chinese grade BFe10-1-1. These plates exhibit excellent resistance to seawater corrosion, biofouling, and stress corrosion cracking. They are manufactured by hot rolling or cold rolling and can be supplied in various thicknesses, widths, lengths, tempers (annealed, half‑hard, full‑hard), and surface finishes (2B, polished, brushed, mirror, chequered).
2. Product Applications
Marine & Offshore: Ship hull sheathing, seawater cooling pipes, condensers, heat exchangers, desalination plants (MSF/MED), offshore platforms, splash zone protection, propeller shafts, pump bodies.
Power Generation: Steam surface condensers, turbine oil coolers, auxiliary cooling systems in nuclear and thermal power plants.
Chemical Processing: Pressure vessels, reactors, evaporators, piping for corrosive chemicals (dilute sulfuric acid, organic acids).
Other: touch surfaces (hospital equipment), architectural cladding, shipbuilding, hydraulic lines, firewater systems.
3.Product Advantages
Outstanding resistance to seawater corrosion and erosion – Self‑renewing oxide film ensures decades of service in tidal and splash zones.
Inherent biofouling resistance – Eliminates need for expensive and toxic anti‑fouling coatings.
High thermal conductivity – Approximately 40–50 W/m·K, enabling compact heat exchanger designs.
Excellent fabricability – Can be bent, rolled, welded (TIG/MIG), and machined using standard equipment.
Good strength‑to‑weight ratio – Yield strength up to 250 MPa (C71500) while maintaining ductility (elongation >25%).
Low life‑cycle cost – Reduced maintenance, inspection, and replacement frequency.
Fully recyclable – Environmentally friendly material with no hazardous substances.
