What is Copper Nickel Flat Bars?

These flat bars are expertly crafted from copper-nickel alloys, often the 90/10 or 70/30 compositions, which give them a distinct set of advantages. This blend provides outstanding resistance to corrosion, especially in saltwater, and makes them highly resistant to biofouling. Mechanically, they offer excellent strength and toughness, maintaining their integrity across a wide range of temperatures. They are also known for good thermal conductivity and are very easy to fabricate and weld using standard techniques.
