What is Copper Nickel Round Bars?

Typically, Copper Nickel Round Bars consist of 70–90% copper and 10–30% nickel, with small amounts of iron and manganese added to enhance strength and corrosion resistance. This well-balanced composition ensures excellent performance in environments rich in chlorides, particularly seawater. The bars boast a tensile strength ranging from 275–450 MPa, a yield strength of 100–150 MPa, and an elongation of 30–45%. They also demonstrate good thermal conductivity, ductility, and weldability, along with impressive resistance to pitting, stress corrosion cracking, and crevice corrosion in challenging environments.
