Hakan Nickel Alloys, based in Istanbul, Turkey, is a dedicated manufacturer and global supplier of top-notch metal products, including Copper Nickel Coils. With a strong emphasis on quality, consistency, and technical precision, the company provides dependable alloy solutions for a variety of industries. Renowned for its customer-focused service and commitment to international standards, Hakan Nickel Alloys offers Copper Nickel Coils that cater to the rigorous demands of marine, power, and industrial sectors. These coils are prized for their resistance to corrosion, thermal stability, and longevity, making them perfect for heat exchange systems, fluid transport, and structural components.
Copper Nickel Coils are typically produced in 90/10 (90% copper, 10% nickel) or 70/30 (70% copper, 30% nickel) blends, both of which boast exceptional resistance to seawater corrosion and erosion. These alloys exhibit tensile strength ranging from 300 to 500 MPa, along with impressive ductility and fatigue resistance. The coils also offer good thermal conductivity and maintain stability across a wide temperature range. Being non-magnetic and resistant to biofouling, they uphold their structural integrity even in harsh environments. Their ease of fabrication, weldability, and reliable mechanical properties make Copper Nickel Coils a trusted option for industrial engineering and marine equipment manufacturing.
