UNS C44300 Admiralty Brass Tube PDF
What is CuZn28Sn1 CZ111 C44300 copper tubing?
UNS C44300 Admiralty Brass, also sometimes referred to as Arsenical Brass, is copper that is alloyed with tin and zinc. Brass 443 tubes have long been used in heat exchangers and condensers because of the good corrosion resistance and excellent heat transfer characteristics of C44300 CuZn28Sn1 CZ111.
Admiralty brass, also known as ASTM B111 UNS C44300, is a copper-zinc alloy with small amounts of tin and trace amounts of other elements. It is commonly used in marine applications due to its high corrosion resistance and excellent thermal conductivity. The seamless tube made from Admiralty brass is manufactured according to ASTM B111 standards, which specify the requirements for seamless copper and copper-alloy tubes for heat exchangers and condensers. These tubes are typically used in a variety of applications, including desalination plants, power plants, and shipbuilding. Admiralty brass seamless tubes are known for their high strength, durability, and resistance to stress corrosion cracking. They are also easy to form and weld, making them a popular choice for various industrial applications. Admiralty brass seamless tubes are a reliable and cost-effective solution for demanding marine and industrial applications that require superior corrosion resistance and thermal conductivity.
