In Chennai, India, Kunj Sheets and Plates is a reputable producer and supplier of premium Copper Nickel 90/10 Foil. We are renowned for providing high-quality metal solutions, and we provide Cu-Ni 90/10 foils, which have exceptional corrosion resistance, particularly in brine and seawater environments. Our foils are made with sophisticated procedures and strict quality control, and they can be customised to meet international standards. Our Copper Nickel 90/10 Foils are used in a variety of industries, including chemical processing, power generation, and the marine industry, due to their exceptional durability, thermal stability, and weldability. In both domestic and international markets, Kunj is dedicated to guaranteeing on-time delivery and client satisfaction.
About 90% copper and 10% nickel make up Copper Nickel 90/10 Foil, with trace amounts of iron and manganese added to improve strength and resistance to corrosion. In addition to having outstanding ductility and elongation of up to 35%, the alloy has a tensile strength of 275–350 MPa and a yield strength of 70–105 MPa. It maintains mechanical integrity in brine and seawater conditions and operates dependably in high-temperature and high-pressure settings. The foil is appropriate for precision engineering and fabrication because it is non-magnetic, has good thermal conductivity, and is simple to form and weld.

Copper-nickel 90/10 foil offers many benefits including exceptional corrosion resistance, especially in seawater and marine environments. It is highly resistant to biofouling, making it ideal for the marine environment. The material also has excellent thermoelectric conductivity, which enhances its application in heat exchangers and electrical components. Copper-nickel 90/10 has durability, excellent strength, form ability and pressure corrosion cracking resistance. Its weldability and ease of manufacture make it versatile for industries such as chemical processing, desalination and aerospace, where reliability under extreme conditions is critical.
Because of its exceptional resistance to biofouling and seawater corrosion, copper nickel 90/10 foil finds widespread use in naval and marine applications. It is perfect for producing heat exchangers, evaporators, and condenser tubes for ships and offshore platforms. The foil is used for thermal and corrosion-resistant components in the desalination and power industries. Chemical plants also use it to handle saline and acidic fluids. It is also appropriate for instrument housings and electronic shielding due to its formability and thermal characteristics. Applications in industry and architecture that demand durability, dependability, and resistance to extreme weather conditions value the foil.
