Copper Alloy Steel B111 C70600-O61 Low Fin Tube Features
Corrosion Resistance: Forms a dense Cu₂O-NiO film; resists seawater (up to 4.5 m/s flow), biofouling, stress-corrosion cracking, and erosion in brackish/marine environments.
Fabricability: O61 temper enables easy bending/flaring; welds well via TIG/MIG/brazing (use ERNiCu-7 filler); cold workable for shaping.
Heat Transfer: Good thermal conductivity (~50 W/(m·K)) suits heat exchangers/condensers.
Durability: Stable performance from -100°C to 200°C; long service life (20+ years) in seawater systems.
Copper Alloy Steel B111 C70600-O61 Low Fin Tube Key Applications
Power Generation: Steam turbine condensers, power plant heat exchangers.
Process Industries: Chemical plant tubular systems, pharmaceutical equipment handling corrosive fluids.
Other: Brackish water piping, distiller tubing, evaporator tubes.
Copper Alloy Steel B111 C70600-O61 Low Fin Tube FAQ
What does O61 temper mean?
Fully annealed (soft) condition for maximum ductility, critical for tube forming and flaring in heat exchanger/condenser assembly.
Can it handle high-velocity seawater?
Yes—resists flow up to 4.5 m/s, better than pure copper or brass.
Recommended welding filler?
Use ERNiCu-7 (AWS A5.7) for TIG/MIG; avoid high-iron fillers to preserve corrosion resistance.
Is it cost-competitive vs. stainless steel?
Higher upfront cost but lower lifecycle cost due to longer service life and less maintenance in marine environments.
What is the max operating temperature?
200°C for long-term service; short-term exposure up to 400°C is acceptable.
Copper Alloy Steel B111 C70600-O61 Low Fin Tube Key Considerations
Fabrication: Annealed O61 tubes require care to avoid overworking; cold forming may need re-annealing.
Joining: Clean surfaces and proper shielding gas (argon) prevent oxidation during welding.
Standards Compliance: Ensure conformance to ASTM B111 for dimensions, mechanicals, and corrosion performance.
Copper Alloy Low Fin Tube B111 C70600-O61 for Evaporator and Condensers
C70600-O61 is the go-to annealed CuNi tube for marine and power applications demanding corrosion resistance plus ductility. Its balanced properties make it reliable for critical seawater cooling and heat transfer systems.
