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, chemical processing, desalination, and offshore platforms. Its Copper Nickel Stud Bolts are engineered for superior corrosion resistance, mechanical strength, and durability. Designed for critical assemblies and piping systems exposed to harsh seawater and chemically aggressive environments, these bolts provide secure, reliable fastening solutions that ensure structural integrity and long-term performance in demanding industrial and marine applications.
Copper Nickel Stud Bolts are typically made from 70/30 or 90/10 copper-nickel alloys, consisting of copper as the base metal with 10–30% nickel, and minor additions of iron and manganese to improve strength and corrosion resistance. These bolts exhibit excellent resistance to seawater corrosion, pitting, and biofouling. Mechanical properties include high tensile strength, moderate hardness, and good ductility, allowing for secure installation and reliable performance under mechanical stress, high pressure, and chemically aggressive marine or industrial conditions.
