A well-known producer and supplier of Copper Nickel 70/30 Circles, Khush Sheets and Plates is situated in Kolkata, India, and provides high-quality non-ferrous metal products for vital industrial uses. Particularly in saltwater and marine settings, our Copper Nickel 70/30 Circles are renowned for their remarkable resistance to corrosion. These circles are produced in accordance with strict national and international quality standards using premium raw materials and precise engineering techniques. Khush Sheets and Plates provides services to the marine, chemical processing, power generation, and heat exchanger manufacturing industries in India and overseas with an emphasis on product dependability, prompt delivery, and customer satisfaction.
About 70% copper and 30% nickel make up Copper Nickel 70/30 Circles, with trace amounts of iron and manganese added for strength and corrosion resistance. The alloy performs exceptionally well in high-velocity marine environments and saltwater. It usually has an elongation of 30–40%, a yield strength of 230 MPa, and a tensile strength of about 520 MPa. These circles are perfect for high-performance structural and piping systems because they are stable under mechanical and thermal stress, have good weldability, and are extremely resistant to biofouling and stress corrosion cracking.
