Jyoti Steels is a prominent supplier and manufacturer of top-quality Copper Nickel Bars from Mumbai, India. We excel in manufacturing high-performance, corrosion-resistant bars for important applications in the marine, chemical, and industrial sectors. Our Copper Nickel Bars are highly appreciated for their superior mechanical properties, thermal stability, and corrosion resistance in seawater. With dedication to accuracy, quality control, and prompt delivery, Jyoti Steels serves both national and international customers, providing assured solutions that match the best in the industry.
Copper Nickel Bars are generally found in two primary grades: 90/10 (90% Copper, 10% Nickel) and 70/30 (70% Copper, 30% Nickel), with minor additions of Iron (0.4–1.0%) and Manganese (0.5–1.0%) for strength and corrosion resistance. These bars have a tensile strength of 350–550 MPa, yield strength of 150–250 MPa, and elongation of 30–40%. The density is around 8.9 g/cm³, with a melting point of 1170°C to 1240°C. Copper Nickel bars have superior resistance to stress corrosion, erosion, and biofouling, as well as good weldability and moderate electrical conductivity.
