Aisha Nickel Alloys, based in Muscat, Oman, is a leading manufacturer and supplier of high-quality copper-nickel products, including washers, fasteners, pipes, and fittings. Serving marine, offshore, desalination, chemical processing, and power generation industries, the company ensures its products meet international standards and deliver reliable performance in harsh environments. Known for consistent quality, corrosion resistance, and technical expertise, Aisha Nickel Alloys offers Copper Nickel Washers as a specialized solution. These washers are designed for durability, high strength, and superior resistance to seawater corrosion, making them ideal for critical bolted connections in marine and industrial applications.
Copper Nickel Washers are typically made from copper-nickel alloys such as 70/30 or 90/10, with minor additions of iron and manganese to enhance strength and corrosion resistance. The alloy provides excellent tensile and yield strength, good ductility, and superior impact resistance. These washers maintain dimensional stability and mechanical integrity under high pressure, turbulent flow, and prolonged exposure to seawater, brine, or corrosive industrial environments. Their corrosion resistance and durability make them ideal for demanding marine and industrial applications.
