Adarsh Nickel Alloys is a well-respected manufacturer and supplier based in Delhi, known for its top-notch Copper Nickel 70/30 tube fittings that are perfect for tough industrial and marine applications. They create these fittings using cutting-edge manufacturing techniques and rigorous quality checks to guarantee precise dimensions, leak-proof performance, and a long lifespan. You can find a variety of types, including elbows, tees, reducers, and connectors, all made to meet international standards and tailored to specific needs, making them a dependable choice for corrosion-resistant piping systems.
The Copper Nickel 70/30 tube fittings are primarily made up of about 70% copper and 30% nickel, with small amounts of iron and manganese added to boost strength and corrosion resistance. This alloy provides greater mechanical strength compared to lower nickel grades, along with impressive toughness and ductility. The fittings are highly resistant to seawater corrosion, biofouling, and erosion, while also maintaining stable tensile and yield properties even under fluctuating pressure and temperature conditions.
