Varun Sheets and Plates is a trusted manufacturer and supplier of Copper Nickel Coil and Slitting Coil, proudly based in Dubai, UAE. We specialize in top-quality copper-nickel alloy coils that are renowned for their outstanding corrosion resistance, particularly in marine and saltwater settings. Our coils come in various grades, including 90/10 and 70/30, and are commonly used in applications like heat exchangers, condensers, shipbuilding, and offshore projects. Manufactured to meet international standards such as ASTM B122, our copper-nickel coils are built for durability, exceptional thermal conductivity, and excellent formability. At Varun, we prioritize precise slitting, consistent quality, and timely delivery to our customers both in the UAE and around the globe.
Copper Nickel Coils and Slitting Coils generally consist of copper (70–90%) and nickel (10–30%), with small amounts of iron and manganese added to enhance strength and corrosion resistance. These alloys boast impressive mechanical properties, with tensile strength ranging from 310 to 500 MPa, and they excel in resisting biofouling and seawater corrosion. Additionally, they offer high thermal stability, low electrical resistivity, and are non-magnetic, making them perfect for both structural and conductive uses in challenging environments.

Copper-nickel coil offer many advantages including exceptional corrosion resistance, especially in sea water and harsh marine environments. They are highly robust, resistant to biofouling, and store energy over a wide temperature range. The excellent thermoelectric conductivity of the alloy makes it ideal for heat exchangers and electrical components. Copper-nickel sockets also exhibit excellent formability, enabling complex shapes without compromising integrity. Properties that resist stress corrosion cracking and oxidation ensure long-term performance in complex applications such as shipbuilding, desalination plants and chemical processing, making it cost-effective and portable to it in the long run
You’ll find Copper Nickel Coils and Slitting Coils widely utilized in marine, chemical, and power generation sectors. Their applications include tubing for desalination plants, ship hulls, heat exchanger components, condenser tubes, and cladding for offshore platforms. In HVAC systems and industrial piping, they provide excellent resistance to scaling and stress corrosion. Thanks to their ease of fabrication and long-lasting resistance to seawater corrosion, copper-nickel coils are the go-to choice for high-performance, maintenance-free applications in demanding and moisture-rich conditions.
