Supports third-party inspection by DNV, ABS, CCS, LR, BV, and others.
Each product is verified to have a nickel content of 9.0%–11.0%.
Virgin materials; service life of over 20 years in seawater systems.
Anti-rust Oil + Plastic Cap + Fumigation-free Wooden Crate
The main chemical constituents of the CuNi90/10 copper-nickel alloy include:
Copper (Cu): Approx. 90%
Nickel (Ni): Approx. 10%
Corrosion Resistance: Exhibits excellent corrosion resistance in seawater, freshwater, and various chemical media.
Electrical Conductivity: Possesses excellent electrical conductivity, making it suitable for electrical equipment.
Thermal Conductivity: Possesses excellent thermal conductivity, making it suitable for heat exchange equipment.
Processability: It exhibits excellent casting properties, allowing for the fabrication of copper-nickel alloy components of various shapes and sizes through casting methods.
Mechanical Properties: Possesses a certain degree of strength and ductility. Suitable for applications requiring the ability to withstand specific levels of pressure and stress.
We never use recycled scrap copper. Only 100% virgin raw materials ensuring impeccable corrosion resistance and lifespan over 20 years.
Our manufacturing processes align with top IACS members (DNV, ABS, CCS). We handle the paperwork, so your vessel passes inspection smoothly.
All fittings are treated with anti-tarnish oil, fitted with plastic end caps, and securely packed in fumigation-free plywood cases to prevent ocean transport damage.
Employing internationally advanced manufacturing processes to ensure high product performance and reliability.
Every stage—from raw material procurement to the shipment of finished products—undergoes rigorous inspection.
Offering comprehensive customization services to meet the specific needs of our clients.
