ASTM B111 C44300 Copper Tube for Condenser, Heat Exchanger
Application
ASTM B111 C44300 copper 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 copper 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 copper
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 copper 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 copper tubes just meets these needs;
although nuclear power plants have more stringent requirements on
materials, C44300 copper tubes are also used in auxiliary systems
of some nuclear power plants, such as for manufacturing cooling
system tubes.
- Food processing field: Because C44300 copper 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 copper tubes are
often used to manufacture roofs, rainwater tubes and other parts
that are susceptible to rain erosion; C44300 copper tubes can also
be used to make various decorations and artworks, such as
sculptures, lamps, etc.
