1. Product Description
Copper Nickel Plate is a copper‑based alloy plate containing nickel as the main alloying element, typically 10% or 30%, with iron and manganese added to improve mechanical properties and corrosion resistance. Standard grades include C70600 (90/10 CuNi), C71500 (70/30 CuNi), and Chinese grade BFe10-1-1. These plates are widely recognized for their exceptional resistance to seawater corrosion, impingement attack, and biofouling. They are produced by either hot rolling or cold rolling processes, and can be supplied in multiple tempers (annealed, quarter‑hard, half‑hard, full‑hard) and surface finishes (2B, polished, satin, mirror, diamond chequered).
2. Product Applications
Marine engineering: Seawater cooling systems, fire main lines, bilge and ballast lines, shipboard condensers and heat exchangers.
Offshore platforms: Risers, splash zone cladding, seawater intake pipes, pump components.
Power plants: Main condensers, low‑pressure feedwater heaters, auxiliary cooling water systems.
Desalination: Evaporator tubes and plates for multi‑stage flash (MSF) and reverse osmosis pretreatment.
Industrial: Chemical tankers, pressure vessels for dilute acids, brewery and distillery equipment.
3.Product Advantages
Superior resistance to seawater corrosion and galvanic attack – Excellent performance when coupled with noble metals if properly insulated.
Natural resistance to marine fouling – Reduces the need for chemical cleaning and mechanical scraping.
Moderate thermal conductivity – Balances heat transfer efficiency with resistance to scaling.
Easy to weld and braze – No preheating required for thin sections; weldments retain corrosion resistance.
High ductility – Allows cold forming, bending, and flanging without cracking.
Long service life – Typical lifespan of 20–30 years in seawater applications.
100% recyclable – Supports sustainable engineering practices.
