Sayam Nickel Alloys, Hyderabad, India, is a trusted manufacturer and supplier of premium copper-nickel alloy products for marine, offshore, and industrial applications. With a focus on 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 Pipes are engineered for superior corrosion resistance, mechanical strength, and long-term durability. Designed for seamless integration into piping systems, these pipes ensure leak-proof connections and reliable performance in harsh environments, making them ideal for applications exposed to seawater, high pressure, and chemically aggressive conditions.
Copper Nickel 70/30 Pipes are composed of 70% copper and 30% nickel, with minor additions of iron (≤2%) and manganese (≤1%) to enhance mechanical strength and corrosion resistance. The alloy offers excellent resistance to seawater corrosion, pitting, and biofouling. These pipes exhibit high tensile strength, moderate hardness, and good ductility, making them suitable for fabrication, bending, and welding. The material maintains dimensional stability under high temperatures and mechanical stress, ensuring long-term performance and reliability in harsh marine and industrial environments.
