Description
Copper Nickel Boiler Seamless Tube ASTM B111 ASME SB111 C71640 CW353H

The material C71640 is a type of copper alloy, specifically categorized under bronze alloys. It is known for its high strength and corrosion resistance, particularly in marine environments.The alloy is sometimes called a nickel bronze because of the substantial nickel content. The material is prized for its durability and is often used in applications where both strength and resistance to corrosion are critical.

Key Properties of C71640 Copper Alloy:

  • Composition: Typically consists of copper (Cu) with a significant amount of nickel (Ni), and small amounts of other elements such as tin (Sn) and iron (Fe).

  • Nickel Content: C71640 typically contains around 6% nickel, which gives it enhanced strength and resistance to corrosion, especially in seawater.

  • Applications: It is commonly used in marine hardware, valves, pump components, and marine engineering due to its excellent corrosion resistance, especially in saltwater environments.

Properties:
- Corrosion Resistance: Excellent performance in marine/saline environments, resisting biofouling and erosion.
- Thermal Conductivity: Suitable for heat exchangers, condensers, and desalination systems.
- Mechanical Strength: Durable under high-stress conditions, often cold-worked or annealed for specific applications.
Standards & Applications:
- ASTM/ASME Standards: ASTM B111 (Standard Specification for Copper-Nickel Alloy Tubes for Condensers and Heat Exchangers).
Common Uses:
- Marine engineering (ship piping, offshore platforms).
- Power plant condensers.
- Desalination and chemical processing equipment.
