Product Specifications

What is CuNiFe 90/10?

CuNiFe 90/10 is a copper-nickel alloy containing approximately:

• Copper (Cu): 88%–90%

• Nickel (Ni): 9%–11%

• Iron (Fe): 1%–2%

• Manganese (Mn): Small Addition

This alloy is specifically designed for long-term seawater service and offers outstanding resistance to marine corrosion and biological fouling.

Product Advantages

• Excellent Seawater Corrosion Resistance

CuNiFe 90/10 performs exceptionally well in seawater environments and provides long-term protection against corrosion.

• Superior Anti-Fouling Performance

The alloy naturally inhibits marine organism growth, reducing maintenance requirements and improving system efficiency.

• Outstanding Erosion Resistance

Ideal for high-flow seawater systems where erosion-corrosion can be a concern.

• Long Service Life

Copper nickel flanges can provide decades of reliable service in harsh marine conditions.

• Excellent Weldability

Suitable for fabrication and installation in shipbuilding and offshore projects.

• Cost-Effective Marine Solution

Compared with higher alloy materials, CuNiFe 90/10 offers an excellent balance between performance and cost.
