Aisha Nickel Alloys, based in Muscat, Oman, is a leading manufacturer and supplier of high-quality copper-nickel products, including bars, pipes, fittings, 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 harsh environments. Known for consistent quality, corrosion resistance, and technical expertise, Aisha Nickel Alloys offers Copper Nickel 70/30 Bars as a premium solution. These bars are designed for durability, excellent seawater corrosion resistance, and high mechanical strength, making them ideal for industrial and marine applications.
Copper Nickel 70/30 Bars are composed of approximately 70% copper and 30% nickel, 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. Copper Nickel 70/30 maintains dimensional stability and mechanical integrity under high-pressure, high-flow, and corrosive seawater or industrial environments. These bars exhibit outstanding resistance to pitting, erosion, and biofouling, making them highly reliable for demanding marine and industrial applications.
