What is Copper Nickel Round Bars?

Copper Nickel Round Bars are typically made up of copper combined with 10% to 30% nickel, often with small amounts of iron and manganese added to boost strength and corrosion resistance. These bars exhibit outstanding mechanical properties, with tensile strength ranging from 450 to 650 MPa, yield strength around 150 to 350 MPa, and elongation between 20% and 40%. The alloy is known for its remarkable resistance to seawater corrosion, high-temperature performance, and durability, making it perfect for applications that demand both mechanical strength and long-lasting reliability in tough or marine conditions.
