Adarsh Nickel Alloys is a trusted manufacturer and supplier of Select Copper Nickel 70/30 Bars in Delhi, providing high-quality bars for demanding industrial and marine applications. These bars are crafted from premium-grade copper-nickel alloys, ensuring uniformity, strength, and corrosion resistance. Known for their excellent resistance to seawater and industrial corrosion, Copper Nickel 70/30 Bars are widely used in harsh environments where durability and reliability are critical. Adarsh Nickel Alloys supplies these bars in various sizes and lengths, catering to industries such as shipbuilding, desalination plants, chemical processing, and power generation, ensuring consistent quality and performance.
Copper Nickel 70/30 Bars consist of approximately 70% copper and 30% nickel, often with small additions of iron and manganese for improved corrosion resistance and strength. This composition provides excellent resistance to pitting, crevice corrosion, and biofouling, especially in seawater. Mechanically, these bars exhibit good tensile and yield strength, moderate hardness, and high ductility. They maintain stability under varying temperatures and pressures, offering excellent thermal and electrical conductivity. The combination of strength, corrosion resistance, and formability makes them suitable for structural and functional components in demanding industrial environments.
