Hindco Steel And Alloys is an enviable brand in the sphere of industrial suppliers and manufacturers of high quality Copper Nickel 70/30 Sheets which matches the high demands of various industries. Fabricated to the requirements of international standards our sheets are made to meet the ASTM B122 specifications and are the UNS C71500. Referred to worldwide as Cu-Ni 70/30, the alloy has 70 percent copper and 30 percent nickel alongside minor amounts of iron and manganese to boost the overall strength level and corrosion resistance.
Its Copper Nickel 70/30 Sheets are also commonly referred to as sheets that are rather resistant to corrosion in the seawater and thus, it is highly adequate to be used in marine and offshore. These sheets have a high weldability, formability, as well as strength, in spite of harsh saltwater exposure.
Copper also possesses inherent antimicrobial properties, which makes Cu-Ni 70/30 sheets also applicable in the shipbuilding industries, heat exchangers, desalination plants, and chemical processing. Hindco Steel And Alloys has made it a point to have all of their sheets manufactured on stringent quality assurance measures which include modern methods of manufacture to ensure superb thickness precision, smooth treatments in addition to having top quality mechanical features.
We have become a major manufacturer of UNS C71500 Copper Nickel Sheets in India and have positioned ourselves as an important supplier & manufacturer of UNS C71500 Copper Nickel Sheets to the domestic and international markets. Due to our production capacity and high inventory we are able to build custom to order characteristics and get products out quickly at the same quality and performance level consistently. All the ASTM B122 Cu-Ni 70/30 Sheets we trade conform to these standards and represent full certification with documentation, all the test reports and compliance certificates.
