Adarsh Nickel Alloys stands out as a reliable manufacturer and supplier based in Delhi, specializing in top-notch Copper Nickel 70/30 nuts designed for tough industrial and marine settings. With a commitment to quality, Adarsh Nickel Alloys ensures that these fasteners are crafted with rigorous quality control, precise threading, and exact dimensional tolerances, guaranteeing secure fastening and a long lifespan. Renowned for their dependability and consistency, the company offers Copper Nickel 70/30 nuts in a variety of sizes and standards, all in line with international specifications. Customers appreciate their products for their exceptional corrosion resistance, mechanical strength, and reliable performance even in harsh, moisture-rich environments.
These Copper Nickel 70/30 nuts are made from an alloy that consists of about 70% copper and 30% nickel, with small amounts of iron and manganese added to enhance strength and corrosion resistance. This unique blend provides greater tensile and yield strength compared to lower-nickel grades while still maintaining good toughness and ductility. The alloy is particularly known for its impressive resistance to seawater corrosion, erosion, and biofouling, along with stable mechanical properties across a wide temperature range, making it perfect for heavy-duty fastening tasks.
