Hot Rolled Copper Nickel 70/30 Alloy Plate CuNi Sheet ASTM B171 C71500 C70600
1. Product Description
Copper Nickel Plate is a high‑strength, corrosion‑resistant copper‑nickel alloy plate intended for demanding aqueous environments. The alloy system is based on copper with nickel as the primary solute, plus iron and manganese to enhance resistance to erosion and high‑velocity flow. Principal grades are 90/10 CuNi (C70600) and 70/30 CuNi (C71500). These plates exhibit excellent resistance to seawater corrosion, stress corrosion cracking, and bio‑settling. They are manufactured via hot rolling and optional cold rolling, with dimensions conforming to ASTM B171, ASME SB171, and EN 1652 standards. Plates can be supplied in annealed, quarter‑hard, half‑hard, and full‑hard tempers, with surfaces ranging from plain mill finish to polished or chequered patterns.
2. Product Applications
Marine propulsion systems: Water‑lubricated stern tube bearing housings, shaft liners.
Desalination pretreatment: Cartridge filter housings, feed water distribution plates.
Hydroelectric power: Turbine runner ring cladding, cooling water strainer plates.
Chemical transport: Lined pipes and vessels for dilute sulfuric acid and acetic acid.
Industrial flooring: Anti‑slip tread plates for offshore cranes, drilling floors, and walkways.
3.Product Advantages
Exceptional resistance to erosion‑corrosion in high‑velocity seawater – Verified in long‑term marine trials at velocities >3 m/s.
Inherent resistance to crevice corrosion – Outperforms many stainless steels in stagnant seawater.
High thermal stability – Mechanical properties remain consistent up to 250°C (short term).
Excellent cold working characteristics – Can be bent to 180° over a radius equal to plate thickness without cracking.
Easy repairability – Damaged plates can be welded or brazed in situ without special procedures.
Long established industry acceptance – Used by major navies and offshore operators for over 40 years.
Environmentally benign – No toxic element release; fully recyclable at end of life.
