Sayam Nickel Alloys, headquartered in Hyderabad, is a leading manufacturer and supplier of high-quality copper-nickel alloy products for marine, offshore, and industrial applications. Renowned for precision engineering, consistent quality, and reliable delivery, the company serves industries such as shipbuilding, desalination, chemical processing, and offshore platforms. Its Copper Nickel 70/30 Fittings are designed to provide superior corrosion resistance, mechanical strength, and durability. Engineered for seamless integration into piping systems, these fittings ensure leak-proof connections and long-term performance, making them ideal for critical applications where exposure to seawater, high pressure, and chemically aggressive environments is common.
Copper Nickel 70/30 Fittings 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. These fittings offer good tensile strength, moderate hardness, and sufficient ductility for installation in piping systems. Their mechanical properties, combined with superior corrosion resistance, make them highly durable under high-pressure, high-temperature, and chemically aggressive marine and industrial conditions.
