UNS C44300 Admiralty Brass Tube PDF
What is ASTM B111 C44300 copper tubing?
C44300 Admiralty Brass Tube & Pipe is made from Copper alloyed with Tin and Zinc. It is sometimes referred to as Arsenical Brass. C44300 Admiralty Brass Tube is primarily used in water heaters, heat exchanger applications and other similar equipment. C44300 Admiralty Brass Tube has good corrosion resistance, excellent heat transfer properties and is also used in Steam Condensers cooled with salt water, fresh water, or brackish water. C443000 Admiralty Brass Tube has additional applications in Oil and Gas systems as well where corrosion resistance is a key attribute. Other applications include Evaporator Tube, Distiller Tube, and Bourdon Tube.

Performance Advantages
Corrosion Resistance: The synergistic effect of tin and arsenic forms a dense oxide film, effectively resisting seawater corrosion and stress corrosion cracking.
Thermal Conductivity: High thermal conductivity combined with high-temperature steam resistance makes it suitable for heat exchange systems.
Formability: The pipes can be processed through cold bending and flaring, and their weldability is superior to leaded brass (TIG welding or brazing is recommended).
Typical Applications
Marine Engineering: Ship condenser tubes, seawater desalination plant piping, subsea valve components.
Energy & Chemical Industry: Condenser tubes in thermal power plants, heat exchanger tubes in oil refineries, cooling systems in nuclear power plants.
Building HVAC: Air conditioning refrigeration copper pipes, hot water delivery pipes, especially suitable for chlorinated water environments.
