ASTM B111 C23000 thick-wall copper tubing, commonly known as red brass or commercial brass, is an alloy consisting of approximately 85% copper and 15% zinc. This alloy is favored for its excellent formability, good corrosion resistance, and high strength, while maintaining the excellent electrical and thermal conductivity characteristic of copper alloys. These properties make C23000 very popular in a variety of applications, particularly decorative and architectural applications.
Features of ASTM B111 C23000 copper water pipe
Excellent formability: C23000 copper alloy is easily cold- and hot-worked and can be formed using various processes, including forging, rolling, drawing, and stamping, making it suitable for producing complex shapes.
Good corrosion resistance: This copper alloy exhibits good corrosion resistance in most environments, particularly to air, water, and some chemicals.
Higher strength: Compared to other commercial brasses, C23000 offers higher strength, making it suitable for structural applications subject to moderate loads. Good Electrical and Thermal Conductivity: While not as good as pure copper, C23000 still possesses electrical and thermal conductivity sufficient for general electrical and heat exchange applications.




Applications of ASTM B111 C23000 Hollow Copper Tube
Decorative Applications: Due to its attractive yellow-red appearance, C23000 is often used in decorative pieces, architectural decoration materials, and artwork.
Construction Industry: Suitable for the manufacture of building elements such as door and window frames, pipes, and roof coverings.
General Industrial Uses: These include the manufacture of radiators, containers, valves, fasteners, and connectors.
Musical Instrument Manufacturing: Due to its excellent sound conductivity, this copper alloy is also used in the manufacture of some musical instruments, such as horns and certain components of brass instruments.
Processing and Fabrication
C23000 copper alloy has good workability and can be processed and formed using conventional metalworking techniques. It is suitable for welding, brazing, and bonding, enabling the fabrication of complex components. Appropriate heat treatment can be used to adjust its mechanical properties to suit different application requirements.
In general, C23000 red brass plays an important role in many fields due to its good comprehensive performance and beautiful appearance. It is a widely used copper alloy material.
