ASTM B111 C70600-O61 Copper Nickel Low Finned Tube , for Heat Exchanger

The ASTM B111 C70600-O61 Copper Nickel Low Finned Tube is a specialized heat exchanger tube made from a 90/10 copper-nickel alloy (90% copper and 10% nickel). This material is widely recognized for its excellent resistance to corrosion, particularly in marine and seawater environments, as well as its superior thermal and mechanical properties.

Key Features:

1. Material Composition (C70600):

· Copper: 88.7% – 91.2%

· Nickel: 9.0% – 11.0%

· Iron: 1.0% – 1.8%

· Manganese: 1.0% max

· Other trace elements within ASTM specifications.

2. Condition: O61

· This indicates the annealed condition, providing excellent workability, ductility, and corrosion resistance.

3. Low Finned Tube Design:

· The low finned structure increases the surface area of the tube, significantly enhancing its heat transfer efficiency. This design is ideal for applications where compact heat exchangers are required.

4. Corrosion Resistance:

· Exceptional resistance to seawater corrosion, biofouling, and stress corrosion cracking.

· Ideal for use in harsh marine and industrial environments.

5. Thermal Conductivity:

· The copper-nickel alloy offers excellent heat transfer capabilities, making it suitable for heat exchangers, condensers, and cooling systems.

6. Mechanical Properties:

· Tensile Strength: 275 MPa (minimum)

· Yield Strength: 105 MPa (minimum)

· Elongation: 40% (minimum)

Applications:

· Marine Industry: Heat exchangers, condensers, and seawater cooling systems.

· Power Plants: Steam condensers and boiler feedwater heaters.

· Chemical Processing: Equipment exposed to corrosive environments.

· Oil & Gas: Offshore platforms and desalination plants.
