ASTM B111 C71640 Copper Nickel Alloy 70/30 Enhanced Heat Transfer, Condenser Tube

C71640, also known as Copper-Nickel 70/30 or CuNi 70/30, is a high-performance copper-nickel alloy that consists of approximately 70% copper and 30% nickel, with small amounts of iron and manganese. This alloy is widely used for its excellent corrosion resistance, particularly in marine and seawater environments. Like other copper-nickel alloys, C71640 is known for its durability, resistance to biofouling, and good mechanical properties, making it suitable for a variety of industrial applications.

Chemical Composition:

  • Copper (Cu): 66.5 - 70%
  • Nickel (Ni): 29 - 33%
  • Iron (Fe): 0.4 - 0.8% (for added strength and improved resistance to seawater corrosion)
  • Manganese (Mn): 1.0% max
  • Other Elements: Trace amounts of sulfur, phosphorus, carbon, and silicon

Key Properties:

  • Corrosion Resistance
  • High Strength and Durability
  • Thermal and Electrical Conductivity
  • Erosion and Abrasion Resistance
  • Weldability and Formability

Applications:

  • Marine Applications:
  • Desalination Plants
  • Oil and Gas Industry
  • Power Generation
  • Chemical Processing
  • Shipbuilding and Naval Applications
  • Automotive and Transportation
  • Environmental Control Systems
