What are Copper Nickel 90/10 Pipe Fittings?

Copper Nickel 90/10 Pipe Fittings are piping components used in industrial piping systems to:

  • Connect pipelines
  • Change flow direction
  • Branch piping systems
  • Control fluid transport

These fittings are made from Copper Nickel 90/10 (Cu-Ni 90/10) alloy, which consists of approximately 90% copper and 10% nickel, offering excellent corrosion resistance, especially in seawater environments.


Chemical Composition (Typical)

  • Copper (Cu): 88.6 - 90.7%
  • Nickel (Ni): 9 - 11%
  • Iron (Fe): 1.0 - 1.8%
  • Manganese (Mn): 0.5 - 1.0%
  • Carbon (C): ≤ 0.05%
  • Lead (Pb): ≤ 0.02%
