ASTM B111 C44300 copper alloy steel seamless tubes complies with ISO standards m-2004 and B171m-2004, as well as ASTM B111/B111M-2009 (American Standard Copper and Copper Alloy Seamless Condenser Tubes and Casings). C44300 tin brass is a high copper alloy that usually has a high copper content and contains a certain amount of tin and other alloying elements such as zinc and trace amounts of arsenic. The addition of these elements gives C44300 tin brass unique properties.
Mechanical properties: It has good mechanical properties, including high tensile strength and elongation. This makes C44300 tube perform well when subjected to mechanical stress such as pressure and stretching.
Corrosion resistance: It has excellent corrosion resistance, especially in environments with corrosive liquids. The addition of trace arsenic can inhibit dezincification corrosion and further improve the corrosion resistance of the alloy. Recent studies have also shown that the addition of trace elements such as boron and nickel can further enhance its corrosion resistance.
Hot and cold processing performance: C44300 tin brass has excellent cold processing performance and is easy to process into various shapes and sizes. At the same time, it also has certain hot processing performance and can be hot pressed, hot rolled and other processes at a certain temperature.

Application:
Marine engineering field: C44300 tubes play an important role in shipbuilding. Their excellent seawater corrosion resistance makes them an ideal material for manufacturing hulls and marine equipment. In particular, they are used to manufacture parts that come into contact with seawater, such as heat exchangers, condensers, evaporators, etc. In offshore oil and gas production, C44300 tubes are also often used to manufacture equipment such as heat exchangers and condensers on offshore platforms, as well as other parts that need to withstand seawater corrosion.
Power industry: C44300 tubes are widely used in inland thermal power plants, especially for manufacturing high-strength, corrosion-resistant heat exchanger condenser tubes. These devices need to be in contact with corrosive media for a long time, and the corrosion resistance of C44300 tubes just meets these needs; although nuclear power plants have more stringent requirements on materials, C44300 tubes are also used in auxiliary systems of some nuclear power plants, such as for manufacturing cooling system tubes.
Food processing field: Because C44300 tubes have good corrosion resistance and hygienic properties, they are also commonly used in the manufacture of food processing equipment, such as pipelines and containers for the manufacture of dairy products, beverages and other foods.
Construction and decoration field: Due to its excellent corrosion resistance, C44300 tubes are often used to manufacture roofs, rainwater tubes and other parts that are susceptible to rain erosion; C44300 tubes can also be used to make various decorations and artworks, such as sculptures, lamps, etc.
