Description

ASTM B111 C70600 Copper-Nickel 90/10 Low-Fin Tube For Heat Exchanger Tube

Product Overview

  • Base Material: C70600 (Cu-Ni 90/10) seamless tube

  • Fin Type: Integral low fins extruded from base tube

  • Standard: ASTM B111 / ASME SB111

  • Application: Sea-water and brackish water heat exchangers, condensers, coolers

Chemical Composition (Cu-Ni 90/10)

Element Content (%)
Copper (Cu) ≥ 88.6 (balance)
Nickel (Ni) 9.0 – 11.0
Iron (Fe) 1.0 – 1.8
Manganese (Mn) ≤ 1.0
Zinc (Zn) ≤ 1.0
Lead (Pb) ≤ 0.05

Mechanical Properties

Property Value
Tensile Strength ≥ 310 MPa (45 ksi)
Yield Strength (0.5% ) ≥ 105 MPa (15 ksi)
Elongation (2 ") ≥ 30 %
Hardness (HRB) ≤ 100

Key Advantages

  1. Superior Corrosion Resistance
    Outstanding performance in seawater, brackish, and cooling-tower water, resisting pitting and biofouling.

  2. Monometallic Construction
    Integral fins eliminate galvanic concerns—no dissimilar-metal corrosion.

  3. High Thermal Conductivity
    Copper-nickel alloy provides better heat transfer than stainless steels.

  4. Mechanical Durability
    Excellent toughness and fatigue resistance under thermal cycling and vibration.

  5. Low Maintenance
    Natural resistance to marine growth yields longer clean-water intervals.

Typical Applications

  • Marine Condensers

  • Seawater-Cooled Heat Exchangers

  • Desalination Plant Coolers

  • Offshore Platform Cooling Systems

  • Power Plant Condensers

  • Chemical and Petrochemical Coolers
