Sayam Nickel Alloys, headquartered in Hyderabad, is a trusted manufacturer and supplier of high-quality copper-nickel alloy products for marine and industrial applications. With a focus on precision engineering, consistent quality, and reliable delivery, the company serves industries such as shipbuilding, offshore engineering, desalination, and chemical processing. Its Copper Nickel 70/30 Flanges are designed for superior corrosion resistance and mechanical strength, providing leak-proof connections in piping systems. Engineered to withstand harsh seawater and chemical environments, these flanges ensure long-term performance and reliability, making them ideal for critical applications requiring durability and minimal maintenance.
Copper Nickel 70/30 Flanges are composed of 70% copper and 30% nickel, with small amounts 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 good tensile strength, moderate hardness, and sufficient ductility for easy installation. These flanges maintain structural integrity under high pressure and temperature, ensuring leak-proof connections. Their combination of mechanical durability and superior corrosion resistance makes them suitable for long-term use in demanding marine and industrial environments.
