What is Copper Nickel Round Bars?

Typically, Copper Nickel Round Bars are made of copper combined with 10% to 30% nickel, and sometimes include small amounts of iron and manganese to boost strength. They are known for their outstanding resistance to corrosion, especially in seawater and acidic environments. On the mechanical side, these bars boast good tensile strength, high ductility, and moderate hardness, which makes them easy to fabricate and shape. They maintain stability even under high thermal and mechanical stress, while also resisting biofouling and pitting, making them a dependable choice in tough conditions where long-lasting durability and low maintenance are crucial.
