Aisha Nickel Alloys, based in Muscat, Oman, is a trusted manufacturer and supplier of high-quality copper-nickel products, including fittings, pipes, and welding consumables. Serving industries such as marine, offshore, desalination, chemical processing, and power generation, the company provides solutions that meet international standards and ensure reliable performance in harsh environments. Known for consistent quality, corrosion resistance, and technical expertise, Aisha Nickel Alloys delivers products that withstand aggressive conditions. Copper Nickel 70/30 Fittings are a key offering, valued for their durability, excellent resistance to seawater corrosion, and suitability for piping systems in marine and industrial applications.
Copper Nickel 70/30 Fittings are alloyed with approximately 70% copper and 30% nickel, with small amounts of iron and manganese to enhance strength and corrosion resistance. This composition provides excellent tensile and yield strength, along with good ductility and impact resistance. The alloy exhibits outstanding resistance to seawater, brine, and marine biofouling, making it highly suitable for aggressive marine and industrial environments. The fittings maintain dimensional stability and mechanical integrity even under prolonged exposure to high salinity and turbulent flow conditions.
