Al Vishwas Nickel Alloys, based in Dubai, UAE, distinguishes itself as a premier manufacturer and supplier of Copper Nickel Coils, providing high-quality solutions for industrial, marine, and chemical uses. These coils are engineered to deliver exceptional corrosion resistance, mechanical strength, and thermal conductivity, making them ideal for demanding operational environments. With an emphasis on precision, Al Vishwas’s Copper Nickel Coils ensure uniform thickness, a superior surface finish, and reliable performance. Frequently used in heat exchangers, condensers, piping systems, and marine equipment, these coils are designed for durability and long service life. Al Vishwas Nickel Alloys combines advanced engineering with strict quality standards to manufacture coils that meet international specifications and industrial requirements.
Copper Nickel Coils are typically composed of 90% copper and 10% nickel (CuNi 90/10) or 70% copper and 30% nickel (CuNi 70/30), with minor quantities of iron and manganese included to enhance strength and resistance to corrosion. They exhibit outstanding tensile strength, ductility, and fatigue resistance, while still preserving strong thermal conductivity and dimensional stability. These properties allow the coils to withstand pressure, thermal cycling, and demanding environments. The combination of flexibility and mechanical strength makes Copper Nickel Coils well suited for forming, bending, and fabrication operations without compromising their performance in industrial, marine, or chemical applications.
