Cupro Nickel 90/10 is a widely used copper alloy containing 90% copper and 10% nickel. This composition offers excellent resistance to seawater corrosion, making it a preferred choice for marine and offshore industries. It also provides superior mechanical strength, good ductility, and excellent thermal as well as electrical conductivity. Another important property of Cupro Nickel 90/10 is its resistance to biofouling, which ensures long-term durability in harsh conditions. Due to its easy weldability and fabricability, it is often used in the manufacturing of heat exchangers, condensers, shipbuilding components, and desalination plants. With its outstanding performance and versatility, Cupro Nickel 90/10 is considered one of the most reliable alloys for demanding industrial and marine applications.
Cupro Nickel 90/10 is valued for its high corrosion resistance in saltwater environments, making it an essential material for marine industries. With 90% copper and 10% nickel, it delivers an ideal balance of strength, toughness, and ductility. This alloy also resists stress corrosion cracking and erosion, ensuring durability in pipelines, valves, and heat exchangers. Its excellent thermal stability allows it to perform well in fluctuating temperatures. Additionally, Cupro Nickel 90/10 provides good weldability and machinability, enabling easy fabrication into complex shapes and components. Because of its non-magnetic properties, it is also used in sensitive equipment where magnetic interference must be minimized. These qualities make it a trusted material for long-term industrial and marine operations.
Cupro Nickel 90/10 offers numerous advantages that make it stand out among other alloys. Its remarkable seawater corrosion resistance ensures long-lasting performance in harsh marine environments. The alloy is easy to weld, bend, and fabricate, allowing manufacturers to create customized components. Its resistance to biofouling reduces maintenance costs and downtime in seawater systems. With good mechanical strength, it performs effectively under high stress and pressure conditions. Additionally, its thermal and electrical conductivity make it suitable for both energy and heat transfer applications. Cupro Nickel 90/10 also shows excellent resistance to hydrogen embrittlement and scaling, ensuring reliability in industrial processes.
