Khush Sheets and Plates is a renowned manufacturer and exporter of Copper Nickel 70/30 Sheets and Plates in Kolkata, India. We strive to offer high-performance corrosion-resistant products that are suitable for use in the marine, chemical, and power industries. Our Copper Nickel 70/30 Sheets and Plates are renowned for their high strength, superior weldability, and seawater corrosion resistance. Produced from high-quality raw materials and the latest production methods, our products satisfy international quality standards. Khush Sheets and Plates aims to provide strong, effective, and economical solutions specific to different industrial applications.
Copper Nickel 70/30 Plates and Sheets contain around 70% of copper and 30% of nickel, along with minor amounts of iron and manganese to improve strength and corrosion resistance. The alloy offers superior mechanical properties such as tensile strength ranging from 320 to 480 MPa and a yield strength of about 120–200 MPa. It also presents satisfactory elongation (30% minimum) and superb resistance to pitting, stress corrosion cracking, and biofouling. The alloy shows no loss of mechanical integrity even under high-temperature, high-pressure, and seawater conditions, fitting it for harsh industrial purposes.

Copper Nickel 70/30 Sheets and Plates find widespread application in marine engineering because they are highly resistant to corrosion and biofouling by seawater. They are used in shipbuilding, condenser tubes, heat exchangers, desalination facilities, and offshore oil and gas platforms. They are also applied in the chemical processing industry, power plants, and cooling systems. Their better weldability and thermal stability enable them for use in piping systems, pressure vessels, and evaporators. Its corrosion resistance and strength in hostile environments guarantee a long service life, which makes it a material of choice for industries with high-performance, corrosion-resistant metal requirements.
