CuNi10Fe1Mn Copper Alloy Sheet - Saltwater Corrosion Resistance 2-6mm Thickness
CuNi10Fe1Mn Copper Alloy Sheets are engineered for marine, offshore, and coastal applications demanding extreme saltwater corrosion resistance, high strength, and long-term durability. With a nickel content of 9–11% and compliance with ASTM B171, NORSOK M-630, and DNV-GL standards, these sheets are ideal for seawater cooling systems, offshore platforms, and shipbuilding. Available in 2–6mm thicknesses, they withstand harsh marine environments while maintaining structural integrity.
Key Advantages:
- Superior Corrosion Resistance: 50+ years of service in seawater (ASTM G48 tested).
- High Mechanical Strength: Tensile strength up to 450 MPa for load-bearing marine structures.
- Biofouling Resistance: Inhibits marine organism growth, reducing maintenance costs.
- Thermal Stability: Performs reliably in -50°C to 250°C environments (ISO 19904-1 compliant).
- Global Compliance: Certified for ASTM B171, DNV-GL, and EU Marine Equipment Directive (MED).
- Eco-Friendly: 100% recyclable and RoHS/REACH-certified.
