Aisha Nickel Alloys, based in Muscat, Oman, is a leading manufacturer and supplier of high-quality copper-nickel products, including fasteners, fittings, pipes, and welding consumables. Serving marine, offshore, desalination, chemical processing, and power generation industries, the company delivers products that meet international standards and ensure reliable performance in aggressive environments. Known for technical expertise, corrosion resistance, and consistent quality, Aisha Nickel Alloys offers Copper Nickel 70/30 Fasteners as a specialized solution. These fasteners are designed for durability, high strength, and excellent resistance to seawater corrosion, making them ideal for critical bolted connections in marine and industrial applications.
Copper Nickel 70/30 Fasteners are composed of approximately 70% copper and 30% nickel, with small additions of iron and manganese to enhance mechanical strength and corrosion resistance. This alloy provides excellent tensile and yield strength, good ductility, and superior impact resistance. The fasteners maintain dimensional accuracy and mechanical stability under high pressure, turbulent flow, and prolonged exposure to seawater, brine, or corrosive industrial environments. Their corrosion resistance, strength, and durability make them suitable for high-performance marine and industrial applications.
