What are Copper Nickel 90/10 Sheets & Plates?

Copper Nickel 90/10 Sheets & Plates are copper-based alloys composed of 90% copper and 10% nickel, also known as UNS C70600.

These materials are widely used in industries requiring good corrosion resistance, thermal conductivity, and resistance to biofouling.

Copper Nickel 90/10 is ideal for moderate marine and industrial applications.

Key Functions:

  • Provide resistance to seawater corrosion
  • Prevent marine biofouling
  • Offer good strength and ductility
  • Ensure long-term performance in harsh environments

Chemical Composition of Copper Nickel 90/10

Copper Nickel 90/10 has a well-balanced composition for corrosion resistance and strength.

Typical Composition:
