1. Product Description
Copper Nickel Plate is a solid solution strengthened copper‑nickel alloy containing approximately 10% or 30% nickel, with small additions of iron and manganese to enhance resistance to erosion and cavitation. The material is known for its stable passive layer in chloride environments, which provides excellent protection against localized corrosion such as pitting and crevice attack. Copper nickel plates are typically manufactured by hot rolling, followed by annealing and pickling. They can also be cold rolled to achieve precision thickness and improved surface quality. Standard product forms include flat plates, chequered (tread) plates, and profiled plates for heat exchangers. Available surface conditions include hot rolled, cold rolled, pickled, polished, and brushed finishes.
2. Product Applications
Marine Cooling Circuits: Main engine seawater coolers, auxiliary diesel generator coolers, central cooling system plates.
Offshore Drilling Rigs: Mud cooler plates, riser tensioner sheathing, BOP control fluid heat exchangers.
Desalination Plants: Brine heater shells, deaerator internals, condensate cooler plates in MED plants.
Fishing Vessels: Ice maker evaporator plates, refrigerated seawater (RSW) system heat exchangers.
Renewable Energy: Cooling plates for offshore wind turbine converters, tidal turbine components.
3.Product Advantages
Outstanding resistance to crevice corrosion and pitting – Passive film remains stable even in stagnant seawater conditions.
Excellent resistance to hydrogen sulfide and ammonia – Suitable for treated sewage outfalls and marine outfalls.
High resistance to cavitation erosion – Ideal for pump impellers and valve seats in seawater service.
Ease of machining and cold forming – Can be sheared, punched, and bent using conventional tooling.
Low maintenance and inspection requirements – Reduced downtime for marine assets.
Cost‑effective over equipment lifetime – Lower total cost of ownership compared to titanium alloys.
Wide acceptance by classification societies – Approved by ABS, DNV, LR, BV, CCS for marine applications.
