Aisha Nickel Alloys, headquartered in Muscat, Oman, is a leading manufacturer and supplier of high-quality copper-nickel products, including sheets, coils, strips, and fittings. Serving marine, offshore, desalination, chemical processing, and power generation industries, the company delivers products that comply with international standards and ensure reliable performance in harsh environments. Known for consistent quality, technical expertise, and superior corrosion resistance, Aisha Nickel Alloys offers Copper Nickel 70/30 Coils as a premium solution. These coils are precisely manufactured to provide excellent durability, corrosion resistance, and dimensional accuracy for critical industrial and marine applications.
Copper Nickel 70/30 Coils consist of approximately 70% copper and 30% nickel, with small additions of iron and manganese to enhance strength and corrosion resistance. The alloy provides excellent tensile and yield strength, good ductility, and superior impact and fatigue resistance. It maintains dimensional stability and mechanical integrity under high-pressure, high-flow, and corrosive seawater or industrial conditions. Copper Nickel 70/30 Coils exhibit outstanding resistance to pitting, erosion, and biofouling while offering good thermal conductivity and workability for fabrication into piping, heat exchangers, and other critical components.
