Sayam Nickel Alloys, Hyderabad, India, is a trusted manufacturer and supplier of premium copper-nickel alloy products for marine, offshore, and industrial applications. Known for precision engineering, stringent quality control, and reliable delivery, the company serves industries such as shipbuilding, desalination, chemical processing, and offshore platforms. Its Copper Nickel Washers are engineered for superior corrosion resistance, mechanical strength, and durability. Designed to provide secure fastening and load distribution, these washers ensure reliable performance in harsh environments. They are ideal for applications exposed to seawater, chemical processes, and high-pressure conditions, delivering long-lasting, maintenance-free service.
Copper Nickel Washers are typically made from 70/30 or 90/10 copper-nickel alloys, consisting mainly of copper with nickel (10–30%) and minor additions of iron and manganese for enhanced strength and corrosion resistance. The alloy offers excellent resistance to seawater corrosion, pitting, and biofouling. Mechanical properties include high tensile strength, moderate hardness, and good ductility, allowing for secure and durable fastening. These washers maintain structural integrity under high-pressure, high-temperature, and chemically aggressive environments, ensuring reliable performance in demanding marine, offshore, and industrial applications.
