Product Overview Copper-Nickel Alloys are recognized for their outstanding corrosion resistance, particularly in marine environments. With added nickel, these alloys offer excellent durability, thermal stability, and resistance to biofouling, making them ideal for challenging applications. Common grades like C70600 and C71500 are widely used in industries that require reliable performance in saltwater and high-temperature conditions, such as marine engineering, power generation, and desalination. Available Grades C70600 – Known as 90/10 Copper-Nickel, offering excellent corrosion resistance and good workability, widely used in marine applications and condensers. C71500 – Known as 70/30 Copper-Nickel, providing higher strength and enhanced corrosion resistance, ideal for more demanding applications in high-temperature and seawater environments. Key Properties Outstanding Corrosion Resistance: Performs well in seawater and other corrosive environments, ideal for marine applications. Thermal Stability: Excellent heat resistance, suitable for applications requiring thermal management. Biofouling Resistance: Inhibits marine growth, reducing maintenance and cleaning requirements in submerged applications. Good Strength and Durability: With the added strength of nickel, these alloys provide long-lasting performance. Excellent Fabricability: Can be easily formed and welded, allowing for versatility in manufacturing. Applications Copper-Nickel Alloys are widely used across industries that demand high durability and corrosion resistance: Marine Engineering: Pipes, valves, and fittings in seawater systems. Power Generation: Heat exchangers, condensers, and piping systems in power plants. Desalination Plants: Tubing and piping systems exposed to saltwater. Shipbuilding: Hulls, seawater intake screens, and pump components. Industrial Equipment: Parts that require both strength and corrosion resistance in harsh environments.
