What is Cupro Nickel 70/30 Plate?

Cupro Nickel 70/30 Plate is a copper-nickel alloy consisting primarily of copper and nickel, known for its exceptional resistance to seawater corrosion and biofouling. It is widely used in marine and offshore industries due to its superior performance in saltwater environments. This alloy also offers excellent thermal conductivity, strength, and resistance to stress corrosion cracking, making it suitable for heat exchangers, condensers, and various industrial applications.

  • Exceptional resistance to seawater corrosion
  • High strength and durability
  • Resistance to biofouling and erosion
  • Excellent thermal conductivity
  • Long service life in harsh environments
  • Low maintenance and high reliability

Working Mechanism

How Cupro Nickel 70/30 Plate Works

Cupro Nickel 70/30 Plates work by forming a protective oxide layer on the surface when exposed to marine environments. This layer acts as a barrier, preventing further corrosion and enhancing the material's durability. The presence of nickel significantly improves resistance to seawater corrosion, making it ideal for marine and offshore structures.
