Corrosion-Resistant Copper Alloy Sheets 1000x2000mm - Marine Engineering Applications
Marine-Grade Copper Alloy Sheets are designed for harsh saltwater environments, offering unmatched corrosion resistance, high strength, and longevity. Available in 1000x2000mm dimensions and compliant with ASTM B171, EN 1652, and DNV-GL standards, these sheets are ideal for shipbuilding, offshore platforms, and desalination plants. Made from C61400 aluminum bronze alloy (CuAl9Fe3), they resist biofouling, pitting, and erosion while maintaining structural integrity under extreme marine conditions.
Key Advantages:
- Superior Corrosion Resistance: Withstands seawater, chlorides, and sulfuric acid (ISO 9227 tested).
- Anti-Biofouling: Inhibits marine organism growth, reducing maintenance costs.
- High Mechanical Strength: Tensile strength up to 750 MPa for load-bearing marine structures.
- Custom Sizes: 1000x2000mm standard sheets ±2mm tolerance + laser-cut custom profiles.
- Global Compliance: Certified for ASTM B171, DNV-GL, NORSOK M-630, and REACH/RoHS.
- Sustainable: 30% recycled content + ISO 14001-certified production.
