C70600 Copper Nickel Product Features
1. Exceptional Corrosion Resistance: Resists seawater, weak acids, saline solutions, and high-temperature oxidation (corrosion rate ≤0.003 mm/a); anti-biofouling in marine environments.
2. Mechanical Excellence: Combines high plasticity (soft-state elongation ≥28%) and strength (hard-state tensile strength ≥550 MPa), suitable for high-load applications.
3. Machinability: Supports cold/hot working, welding (TIG/MIG), and stamping; surface finish up to Ra 0.1μm.
4. Temperature Adaptability: Operates reliably from -100°C to 371°C with no low-temperature embrittlement.

Core Advantages
1. Industry-Leading Corrosion Resistance: Resists stress corrosion cracking and high-temperature dezincification, ideal for harsh environments (seawater, chemical media).
2. High Machining Flexibility: Compatible with stamping, welding, and forging for diverse industrial needs.
3. Cost-Efficiency: Lower cost than high-nickel alloys (e.g., C71500) with performance close to BFe30-1-1.
Product Applications
1. Marine Engineering: Seawater desalination evaporator tubes, ship condensers, offshore platform components.
2. Chemical Equipment: Petrochemical coolers, reactors, heat exchanger sleeves.
3. Power Industry: Power plant steam turbine condensers, nuclear cooling systems.
4. Aerospace: Hydraulic system pipelines, engine components.
Processing Guidelines
1. Welding: Prefer TIG or laser welding; interpass temperature ≤100°C to avoid hot cracking.
2. Annealing: Post-cold working, anneal at 650-750°C to relieve stress; hot working temperature: 900-960°C.
3. Environmental Requirements: Welding humidity <90%; preheat to 15°C if ambient temperature is <0°C.
