Copper Nickel 90/10 pipe

Jul 09, 2025

Copper Nickel 90/10 pipe is composed of 90% copper and 10% nickel, with trace elements added to enhance its mechanical properties. The presence of nickel significantly improves the corrosion resistance of copper, especially in marine environments. These pipes are typically manufactured as seamless and cold-drawn, and their strength can be further enhanced through cold working processes after production.

Copper has long been a trusted material for water piping, and while various alternatives exist today, Copper Nickel 90/10 remains a preferred choice for demanding applications. This alloy is particularly valued in marine engineering, especially for piping systems on ships and offshore oil platforms, due to its excellent resistance to seawater corrosion and biofouling.
