Sayam Nickel Alloys, Hyderabad, India, is a trusted manufacturer and supplier of high-quality copper-nickel alloy products for marine, offshore, and industrial applications. Known for precision engineering, strict quality control, and timely delivery, the company serves industries such as shipbuilding, desalination, chemical processing, and offshore platforms. Its Copper Nickel 70/30 Sheets and Plates are engineered for superior corrosion resistance, mechanical strength, and long-term durability. Designed for ease of fabrication and integration, these sheets and plates are ideal for applications exposed to seawater, high pressure, and chemically aggressive environments, ensuring reliable and long-lasting performance.
Copper Nickel 70/30 Sheets and Plates are composed of 70% copper and 30% nickel, with minor additions of iron (≤2%) and manganese (≤1%) to enhance strength and corrosion resistance. The alloy provides excellent resistance to seawater corrosion, pitting, and biofouling. Mechanical properties include high tensile strength, moderate hardness, and good ductility, making the sheets and plates suitable for forming, welding, and fabrication. They maintain dimensional stability and mechanical integrity under high temperatures and aggressive environmental conditions, ensuring long-term durability and reliable performance in marine and industrial applications.
