Our Copper Nickel 70/30 Sheets and Plates are perfect for chemical and marine applications because of their exceptional strength, superior corrosion resistance, and thermal conductivity. Our products are guaranteed to meet international standards thanks to our state-of-the-art manufacturing facilities and rigorous quality checks. Kunj Sheets and Plates is dedicated to providing high-performance, long-lasting, and reasonably priced metal solutions with timely delivery and attentive service, and it has earned the trust of customers in the shipbuilding, power generation, and offshore industries.
Copper Nickel 70/30 Sheets and Plates are made up of 70% copper and 30% nickel, with trace amounts of iron and manganese added for strength and corrosion resistance. These plates offer superior stress corrosion and erosion resistance, as well as remarkable resistance to biofouling and seawater. They have an elongation rate of about 30%, a yield strength of about 130–200 MPa, and a tensile strength of 320–500 MPa. The alloy is appropriate for structural and thermal transfer applications in challenging conditions because it exhibits exceptional formability, weldability, and toughness while maintaining mechanical stability at high temperatures.
