Why are Copper-Nickel Alloy Materials indispensable in shipbuilding?

The reason why Copper-Nickel Alloy Materials are indispensable in the shipbuilding industry is mainly based on the following reasons:
1. Excellent corrosion resistance
Resistant to seawater erosion corrosion: Copper-nickel alloys, especially iron-nickel alloys such as BFe10-1-1 (C70600) and BFe30-1-1 (C71500), have super strong resistance to seawater erosion corrosion. This property enables copper-nickel alloys to remain stable for a long time in the marine environment, reducing material failure and replacement costs caused by corrosion.
Wide corrosion resistance range: When the mass fraction of nickel is between 30% and 10%, these alloys have a wide passivation range and the corrosion resistance. This enables them to cope with various complex marine environments and ensure the integrity and safety of ship structures.
2. Excellent mechanical and processing properties
High strength and toughness: Copper-nickel alloys not only have high tensile strength and yield strength, but also show good plasticity and toughness. This enables them to withstand various mechanical challenges encountered by ships during navigation, such as wave impact, ship shaking, etc.
Good hot and cold processing performance: Copper-nickel alloys show good stability during hot and cold processing, and their mechanical properties and corrosion resistance will not be affected by phase change. This is conducive to material processing and forming during shipbuilding.
3. Wide range of application areas
Ship cooling system: Copper-nickel alloys are widely used in the cooling water pipe system of the main and auxiliary engines of ships. Its heat transfer performance and corrosion resistance ensure the stable operation of the cooling system and extend the service life of the ship.
Offshore oil production platforms and power plant equipment: Copper-nickel alloys are also used in fire protection pipelines on offshore oil production platforms, heat exchangers in power plants, and condensers in coastal nuclear power plants. These applications further prove the importance and irreplaceability of copper-nickel alloys in the field of marine engineering.
4. Economic and environmental protection
Long-term cost-effectiveness: Although the initial investment of copper-nickel alloys may be high, its corrosion resistance and long-term stability make it significantly cost-effective during its service life. Reduce the cost of repair and replacement due to corrosion.
Environmental advantages: The use of copper-nickel alloys reduces waste and pollution caused by material failure, which meets the requirements of modern shipbuilding for environmental protection and sustainable development.
In summary, copper-nickel alloy materials are indispensable in the shipbuilding industry due to their corrosion resistance, mechanical and processing properties, wide application fields, and economic and environmental protection. These characteristics make copper-nickel alloys one of the important materials in the field of marine engineering, providing a strong guarantee for the safe, stable and efficient operation of ships.
