ASTM B111 C71500 Copper Nickel Tubes
Copper Nickel 70/30, or Copper Nickel Alloy C71500, is a combination of copper and nickel that creates an alloy with excellent corrosion resistance. Copper Nickel 70/30 and 90/10 Pipes are especially useful for piping in seawater systems such as marine applications due to their outstanding strength and durability against saltwater corrosion.
These pipes offer excellent strength and corrosion resistance, making them ideal for marine applications, such as seawater cooling systems, saltwater transportation, heat exchangers, and more. One of the Advantages of Copper Nickel 90/10 pipes is that they also provide superior formability, which makes them an ideal choice for complex installations or tight spaces.
Uses of Copper Nickel 70/30 and 90/10
Copper Nickel 70/30 (C70600) is commonly used in marine applications such as shipbuilding, offshore oil and gas production, and coastal power plants. It's also used in desalination plants, condenser tubing, and chemical processing.
Copper Nickel 90/10 (C70600) is also commonly used in marine applications such as shipbuilding, offshore oil and gas production, and coastal power plants. It's also used in desalination plants, condenser tubing, and chemical processing. Because of its higher nickel content, it provides better corrosion resistance in harsh environments than 70/30 alloys.
Both alloys are also used in heat exchangers, evaporators, and distiller tubes and in manufacturing coins, medals, and other decorative items.
Difference Between Copper Nickel 70/30 and 90/10
The primary difference between Copper Nickel 70/30 pipes and Copper Nickel 90/10 pipes lies in their chemical composition. Copper Nickel 70/30 comprises approximately 70% copper and 30% nickel, while Copper Nickel 90/10 has a higher content of copper at roughly 90%, paired with only 10% nickel. Another critical difference between Copper Nickel 70/30 and Copper Nickel 90/10 is their respective applications. Nickel 70/30 is typically used for items exposed to seawater, such as marine fittings and hulls, while 90/10 is better suited for freshwater applications, like cooling systems and condenser tubes also Both alloys are also suitable for industrial piping systems or tubing where corrosion resistance is required.
