ASTM B111 C71500 Copper Nickel Alloy Seamless Tube for Heat Exchangers

ASTM B111 C71500 Copper Alloy Steel Seamless Tube For Power Plants

The ASTM B111 C71500 is a seamless tube made from a Copper-Nickel alloy, commonly referred to as 70/30 Copper-Nickel due to its composition of approximately 70% copper and 30% nickel. It also contains small amounts of iron and manganese, which enhance its strength and corrosion resistance.

Key Features:

• Excellent Corrosion Resistance
  C71500 is known for its exceptional resistance to seawater corrosion, making it ideal for marine and offshore applications.

• High Strength and Durability
  The addition of nickel improves its mechanical properties, providing high strength and durability even in extreme environments.

• Good Thermal and Electrical Conductivity
  Despite its high nickel content, it retains favorable thermal and electrical conductivity.

• Ease of Fabrication
  This alloy can be easily formed, welded, and fabricated into complex shapes.

Chemical Composition:

• Copper (Cu): 69%-71%
• Nickel (Ni): 29%-31%
• Iron (Fe): 0.4%-1.0%
• Manganese (Mn): ≤ 1.0%

Applications:

• Marine Industry: Used in heat exchangers, condensers, and piping systems exposed to seawater.
• Power Plants: Ideal for cooling systems and condensers.
• Desalination Plants: Suitable for evaporator and condenser tubing.
• Chemical Processing: Resistant to chemical corrosion, making it useful in industrial applications.
