Detailed Information
What is the difference between 90/10 and 70/30 copper-nickel?
CuNi 90/10 is more economical and offers good corrosion resistance and thermal conductivity, ideal for standard marine piping and heat exchangers. CuNi 70/30 provides higher strength and better performance in aggressive or high-velocity seawater, commonly used in offshore and desalination systems.
