Aisha Nickel Alloys, based in Muscat, Oman, is a trusted manufacturer and supplier of high-quality copper-nickel products, including pipes, fittings, and welding consumables. Serving marine, offshore, desalination, chemical processing, and power generation industries, the company provides solutions that 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 90/10 Fittings as a key product. These fittings are highly durable, resistant to seawater corrosion, and ideal for piping systems in both industrial and marine applications.
Copper Nickel 90/10 Fittings consist of approximately 90% copper and 10% nickel, with small amounts of iron and manganese to enhance strength and corrosion resistance. This alloy provides excellent tensile and yield strength, along with good ductility and impact resistance. The material exhibits outstanding resistance to seawater, brine, and marine biofouling. It maintains dimensional stability and mechanical integrity even under prolonged exposure to high salinity, turbulent flow, and temperature variations, making it highly suitable for demanding marine and industrial environments.
