CuNi 70/30 Copper Nickel Plate for Desalination Plant ASTM B171 C71500 Sheet
1. Product Description
Copper Nickel Plate is a copper‑nickel‑iron‑manganese alloy plate offering superior resistance to high‑velocity seawater and brackish water corrosion. The two primary grades are CuNi90/10 (UNS C70600) and CuNi70/30 (UNS C71500). The alloy’s protective surface film forms rapidly and remains stable even under turbulent flow conditions. Copper nickel plates are available in hot rolled (HR) and cold rolled (CR) conditions, with various heat treatments (soft, half‑hard, hard). Typical surface finishes include mill finish, pickled, polished, and chequered (raised pattern) for anti‑slip flooring. These plates are widely used in components exposed to seawater, brine, and organic acids.
2. Product Applications
Shallow water shipbuilding: Bilge keel plates, sea chest covers, rudder bearing housings.
Coastal infrastructure: Tidal turbine blades, lock gate facings, water intake screens.
Oil refineries and petrochemicals: Air cooler tube plates, sour water stripper linings.
Waste heat recovery: Economizer plates in exhaust gas boilers on marine vessels.
General corrosion resistant flooring: Diamond chequered plates for walkways, ramps, and stair treads on offshore platforms.
3.Product Advantages
Superior resistance to impingement attack in flowing seawater – Tested at velocities up to 4.0 m/s for C71500 without measurable erosion.
Excellent anti‑corrosion properties in polluted seawater – Tolerates intermittent sulphide pollution without accelerated attack.
High tensile and fatigue strength – Allows thinner gauge plates compared to stainless steel for same design load.
Easy to solder and braze – Compatible with silver‑based brazing alloys for electrical and piping joints.
Good impact toughness at low temperature – Suitable for cryogenic marine applications down to −196°C.
Fully compatible with standard copper alloy fittings – No galvanic concerns when joined to copper‑nickel elbows or flanges.
One‑step protective oxide formation – No need for chemical passivation treatments before service.
