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
CuNiFe 90/10 performs exceptionally well in seawater environments and provides long-term protection against corrosion.
The alloy naturally inhibits marine organism growth, reducing maintenance requirements and improving system efficiency.
Ideal for high-flow seawater systems where erosion-corrosion can be a concern.
Copper nickel flanges can provide decades of reliable service in harsh marine conditions.
Suitable for fabrication and installation in shipbuilding and offshore projects.
Compared with higher alloy materials, CuNiFe 90/10 offers an excellent balance between performance and cost.
