In Chennai, India, Kunj Sheets and Plates is a well-known producer and supplier of copper nickel channels, serving a wide range of industrial sectors. Our dedication to accuracy and quality is well-known, and we provide Copper Nickel Channels in a range of grades, including 90/10 and 70/30, which are highly prized for their exceptional resistance to corrosion, especially in chemical and marine environments. In order to guarantee exceptional dimensional accuracy, strength, and durability, our products are manufactured utilising cutting-edge technology. Kunj Sheets and Plates provides specialised solutions that satisfy exacting industry standards and particular customer needs, catering to both domestic and international markets.
90/10 (90 percent copper, 10 percent nickel) and 70/30 (70 percent copper, 30 percent nickel) are the two primary grades of copper nickel channels. Small quantities of iron and manganese are also included in these alloys for strength and corrosion resistance. With tensile strengths of 275–370 MPa and yield strengths of 120–150 MPa, they demonstrate exceptional resistance to brine and seawater. 30–40% elongation is the range. Additionally, they are ideal for forming, welding, and long-term service in harsh environments due to their moderate hardness, good ductility, and thermal stability.

Copper and nickel channels have many advantages, including excellent corrosion resistance, especially in marine environments, making them ideal for seawater use and energy a superiority and durability even under extreme conditions. Copper-nickel alloys are more resistant to biocorrosion, reducing maintenance costs. These materials also exhibit excellent thermoelectric conductivity, making them suitable for heat exchangers and electrical applications. In addition, the life of the copper-nickel alloy is extended, eliminating the need for frequent replacement. Their superior equipment ensures ease of manufacture, providing versatile solutions for a range of industrial applications including plumbing, shipbuilding and offshore installations.
Because of their exceptional resistance to corrosion, erosion, and biofouling, copper nickel channels are widely used in marine engineering for seawater piping systems, condenser tubes, heat exchangers, and desalination plants. Additionally, they are used in shipbuilding, offshore oil and gas platforms, and naval applications where a long service life in harsh conditions is crucial. These channels are utilised in cooling circuits and pressure vessels in the chemical processing and power industries. Additionally, copper nickel channels are used in architectural structures, medical devices, and coinage. In these fields, where corrosion resistance and structural integrity are crucial, they provide both practical and aesthetic benefits.
