Based in Kolkata, India, Khush Sheets and Plates is a well-known producer and supplier of high-quality Copper Nickel 90/10 Circles. We are dedicated to providing premium Cu-Ni 90/10 alloy circles that satisfy the demanding requirements of heat transfer, industrial, and marine applications. Our Copper Nickel 90/10 Circles are renowned for their long service life in challenging conditions, exceptional thermal conductivity, and outstanding resistance to corrosion. Our products are made in accordance with national and international standards using quality-tested materials and sophisticated manufacturing techniques. With each order, Khush Sheets and Plates guarantees prompt delivery, affordable prices, and total client satisfaction.
90% copper and 10% nickel make up Copper Nickel 90/10 Circles, with trace amounts of iron (up to 1.4%) and manganese (up to 1%) added for strength and corrosion resistance. In seawater environments, these circles have outstanding ductility, good tensile strength (approximately 275–350 MPa), and superior resistance to stress corrosion and erosion. They are very formable and weldable and have good heat conductivity. They are perfect for applications in harsh environments needing long-term dependability, durability, and minimal maintenance because of their mechanical stability and resistance to marine biofouling.

Because of their remarkable resistance to biofouling and saltwater corrosion, copper nickel 90/10 circles are used extensively in the industrial, offshore, and marine sectors. Condenser plates, pump parts, flanges, gaskets, and tube sheets in shipbuilding and desalination facilities are typical uses. They are utilised in pressure vessels, evaporators, and heat exchangers in power plants. They are also appropriate for industrial piping and HVAC systems due to their superior formability and thermal conductivity. These circles are also utilised in fuel systems, seawater cooling systems, and chemical processing equipment, where long-term dependability, high strength, and resistance to corrosion are crucial.
