Copper Nickel 70/30 Flanges are trusted for their exceptional resistance to seawater, corrosion, and high-pressure environments. Known for their durability and stable performance, these flanges are commonly used in marine, offshore, and industrial systems that rely on strong, leak-free connections. With a balanced mix of strength and flexibility, Copper Nickel 70/30 Flanges handle harsh conditions with ease, making them ideal for saltwater pipelines, cooling systems, and heat exchangers. Their smooth finish, long lifespan, and reliable performance make them a preferred choice for engineers looking for secure and dependable piping components in challenging applications.
Copper Nickel 70/30 Flanges are composed of 70% copper and 30% nickel, with small additions of iron and manganese for enhanced strength and corrosion resistance. This alloy offers excellent toughness, high ductility, and strong resistance to erosion and biofouling in seawater environments. Mechanically, it maintains stability under varying temperatures and pressure levels, ensuring dependable performance in demanding applications. The material’s superior thermal conductivity and resistance to stress corrosion cracking make Copper Nickel 70/30 Flanges ideal for long-lasting and reliable piping systems in harsh marine and industrial conditions.
