An alloy with 60 to 90% copper is known as cupronickel or copper-nickel. Cupro Nickel 70-30 Valves & Tubes are utilized in heat exchangers, condensers, and cryogenic applications because of their excellent corrosion resistance and resistance to saltwater corrosion. The ability of Copper Nickel 70/30 Seamless Pipe to withstand high mechanical stress at high temperatures and find use in the cement and oil refining sectors are further advantages.
Features of Copper Nickel 70/30 Tube
There are two different kinds of copper-nickel alloys: 70/30 and 90/10. Due to the substantial levels of manganese and iron present, copper-nickel 70/30 is extremely resistant to corrosion caused by seawater.
A metal used in cryogenic applications is cupro-nickel. Its great ductility retention and thermal conductivity at very low temperatures make it the perfect material for heat exchangers in freezing facilities when utilized in cryogenic processing and storage equipment.
Despite having a high copper content, cupronickel exhibits a silvery chrome tint. Copper-nickel is utilized in seawater systems and maritime equipment such as pipelines, heat exchangers, and condensers due to its exceptional corrosion resistance. High-quality hulls, shafts, and propellers are frequently constructed from this material. Other uses for this material include electrical, chemical, petrochemical, and military equipment.
Applications for copper-nickel alloys are listed:
- Desalination equipment
- A hydraulic system
- aquaculture fish cages
- Condensers and heat exchangers
- ocean water pipes
- systems for offshore firewater
- tubes for ships and power plants
- ship hull pumps, valves, sheathing, and fittings
Copper Nickel Tube Types
- The moderate strength, workability, formability, and weldability of the copper-nickel alloy are well recognized. The copper alloy C715 is often referred to as nickel-copper 70/30 due to its 30% nickel content. High temperature, high pressure, high speed, and turbulent flow applications are all well suited for nickel-copper 70/30 tubing.
- Due to its low iron content (up to 0.5%), the C715 alloy is excellent for use in maritime and industrial applications since it resists both general corrosion and specific stress corrosion cracking.
- Because they include 10–30% nickel, forged copper-nickel alloys like copper–nickel tubes 90/10 are perfect for the maritime environment. Iron and manganese are also added in small amounts to improve corrosion resistance. Because of its excellent ductility and endurance, it is a widely used grade.
- Outstanding welding and manufacturing capabilities are provided by Cupro Nickel. It features a built-in resistance against biofouling. It is perfect for use in low to very low temperatures because of a number of its exceptional characteristics. It exhibits unparalleled antimicrobial properties. In just two hours, 99 percent of bacteria may be destroyed.
