ASTM B111 / ASME SB111 UNS C44300 Admiralty Brass Tube for Heat Exchanger and Condenser
C44300 is a type of admiralty brass, which is a copper-zinc alloy with small amounts of other elements such as tin and arsenic. Admiralty brass is known for its excellent corrosion resistance and high resistance to dezincification, making it suitable for various applications in water systems and marine environments.
The seamless tubes manufactured according to the ASTM B111 C44300 specification are typically used in heat exchangers, condensers, and other applications where good thermal conductivity and corrosion resistance are required. Some of the key properties of C44300 seamless tubes include high thermal conductivity, good mechanical strength, and excellent resistance to stress corrosion cracking. These tubes are capable of withstanding high temperatures and pressures commonly encountered in heat transfer applications.
