Overview: C70600 tubing is a copper-nickel alloy material with excellent comprehensive performance. It exhibits good strength and ductility at room temperature, while maintaining high mechanical properties even at high temperatures. This material possesses high thermal conductivity, excellent corrosion and erosion resistance, and forms a multi-layered protective film, particularly in flowing seawater, significantly enhancing its long-term durability. These characteristics make it an ideal material for marine condensers, coolers, and heat exchangers.
Application:
1. Marine condensers,coolers,and heat exchangers: Their excellent resistance to seawater corrosion and erosion, combined with high thermal conductivity, ensures long-term, efficient, and stable operation of equipment in harsh marine environments, significantly reducing leakage and maintenance costs caused by corrosion.
2. Piping systems (including pipes, fittings, and flanges): Used for transporting seawater, brackish water, and other corrosive media. C70600’s good strength, ductility, and corrosion resistance can withstand the pressure and flow corrosion of the piping system, and the protective film it forms further ensures the long-term sealing and service life of the entire system.
3. Offshore wind turbine structures: Primarily used for internal cooling water systems, hydraulic pipelines, and structural connections. Its superior resistance to seawater corrosion effectively copes with the extreme environments of high salt spray and high humidity at sea, providing reliable protection for critical auxiliary systems of wind turbines.
4.Steel structure anti-corrosion cladding: Applied in plate form to the tidal and underwater areas of steel structures such as offshore platforms, bridges, and docks. As a “sacrificial” cladding, it can provide long-term and reliable cathodic protection for critical steel structures through its excellent corrosion resistance, greatly extending the service life of the structures.
Alloy Advantages: The material we provide is CuNi10Fe1Mn/C70600, mainly containing copper, nickel (9%-11%), iron (1.0%-1.8%), and manganese (max. 0.05%). This material has the following advantages:
- Excellent resistance to seawater corrosion and erosion: C70600 automatically forms a dense, stable, and self-healing protective film in flowing seawater.
- Excellent mechanical properties (room temperature to high temperature): This material exhibits a good balance of strength and toughness at room temperature, making it easy to process and install.
- Good processing and welding properties: This alloy possesses good hot working and cold forming capabilities, and can be manufactured into tubes, plates, rods, etc., using conventional processes. Its welding performance is excellent, allowing for reliable connections using various welding methods.
Manufacturing Process:
1.Melting and Continuous Casting: For hollow products such as pipes, vertical continuous casting technology is often used to directly produce hollow ingots.
2.Plastic Processing: The cast billet is processed into the required shape and size through plastic deformation.
3.Heat Treatment: Heat treatment is the core step in controlling the final properties.
4.Welding: Appropriate beveling, welding materials (matching copper-nickel welding wire/electrode), and process parameters are required. Post-weld stress-relief annealing is often performed to ensure the corrosion resistance of the joint.
