What is the use of cupronickel?
Robert Miller
Updated on April 10, 2026
Copper-nickel (also known as cupronickel) alloys are widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability. They have provided reliable service for decades while offering effective solutions to today’s technological challenges.
Is cupro nickel valuable?
