Product Description
UNS C71500 CuNi 70/30 Plate Hot Rolled Copper Nickel Sheet ASTM B171 Oil & Gas Grade
1. Product Description
Copper Nickel Plate is a copper‑nickel‑iron‑manganese alloy plate designed for reliable service in marine, brackish, and industrial cooling water systems. The two predominant alloys are UNS C70600 (CuNi90/10) and UNS C71500 (CuNi70/30), also supplied as Chinese grades BFe10‑1‑1 and BFe30‑1‑1. The material develops a thin, adherent, and stable protective oxide layer upon exposure to water, providing excellent resistance to general corrosion, pitting, and crevice corrosion. Plates are manufactured by hot rolling (thickness ≥4 mm) or cold rolling (thickness 0.3–3.5 mm). Heat treatment (annealing) is applied to achieve uniform mechanical properties and optimal corrosion performance. Surface finishes include hot rolled descaled, cold rolled bright (2B), polished to various grits, brushed, and chequered (diamond pattern). All plates conform to ASTM B171, ASME SB171, EN 1652, or GB/T 15272.
2. Product Applications
-
Shipboard seawater systems: Central cooling system plates, ballast water treatment unit internals, firewater pump bases.
-
Coastal desalination plants: Brine heater shells, MSF flash chamber liners, distillate collection trays.
-
Offshore drilling rigs: Mud cooler plates, shale shaker screen support plates, BOP accumulator mounting plates.
-
Marine propulsion: Water‑lubricated stern tube bearing shells, thrust pad plates, rudder carrier liners.
-
Coastal chemical plants: Evaporator plates for caustic soda concentration, crystallizer lining plates.
-
Renewable marine energy: Wave energy converter (WEC) structural panels, tidal stream turbine nose cones.
3.Product Advantages
-
Excellent resistance to erosion‑corrosion in sand‑laden water – Maintains low corrosion rates even with suspended solids.
-
High resistance to hydrogen embrittlement – Compatible with cathodic protection systems without risk of cracking.
-
Good weldability in all positions – Suitable for field repairs using GTAW or SMAW without preheat.
-
Low frictional coefficient against steel and bronze – Reduces wear in sliding applications (bearings, guides).
-
Stable mechanical properties in chlorinated water – No degradation from residual chlorine (up to 2 ppm).
-
Can be roll‑bonded to steel for cost‑effective bi‑metal plates – Combines strength of steel with corrosion resistance of CuNi.
-
ISO 9001 certified production with full traceability – Each plate marked with heat number and dimensions.
