ADMIRALTY BRASS C44300 O61 COPPER ALLOY STEEL TUBE B111 / SB111

 

 

Overview

 

C44300 is a type of copper alloy that is commonly referred to as "Admiralty Brass." It is known for its excellent corrosion resistance, high thermal conductivity, and good mechanical properties. C44300 tubes, specifically, are tubes made from this alloy. Here are some key points about C44300 tubes:

  • Corrosion Resistance: C44300 tubes exhibit good resistance to corrosion, making them suitable for various applications where exposure to corrosive environments is expected. They can withstand seawater, brackish water, and other corrosive fluids.
  • Thermal Conductivity: C44300 tubes have high thermal conductivity, making them ideal for applications that involve heat transfer. They are commonly used in heat exchangers, condensers, and other similar applications where efficient heat transfer is crucial.
  • Mechanical Properties: C44300 tubes offer good mechanical properties, including moderate strength and ductility. This makes them easier to form, bend, and fabricate into desired shapes and sizes.
  • Applications: C44300 tubes find applications in various industries, including marine, HVAC (heating, ventilation, and air conditioning), power generation, and chemical processing. Some specific applications include heat exchangers, condensers, evaporators, oil coolers, and refrigeration systems.
  • Weldability: C44300 tubes can be easily welded using common methods such as brazing, soldering, and gas tungsten arc welding (GTAW/TIG). This allows for convenient installation and connection within the system.
  • Availability: C44300 tubes are commercially available in different sizes and forms, including straight lengths, coils, and custom configurations. This provides flexibility in designing and constructing heat transfer systems.

When considering the use of C44300 tubes, it is important to consult with engineers, manufacturers, or industry professionals to determine the most suitable tube size, thickness, and design for your specific application requirements. They can provide guidance on material compatibility, installation techniques, and ensure optimal performance of the heat transfer system.
