ASTM B111 C23000 copper pipe for hot water is a common copper-zinc alloy (red brass). Due to its excellent workability, corrosion resistance, and electrical and thermal conductivity, it is widely used in construction, electrical engineering, and mechanical applications. The following is an analysis of its key properties:
Chemical Composition of ASTM B111 C23000 Refrigeration Copper Tubing
C23000 brass is primarily composed of copper (Cu) and zinc (Zn), with the Cu content ranging from 84.0% to 86.0%, and the Zn content making up the remainder. Additionally, trace amounts of impurities such as lead (Pb) and iron (Fe) (total ≤0.05%) may be present to ensure material purity and performance stability.
Mechanical Properties of ASTM B111 C23000 Refrigeration Tubing
- Tensile Strength: ≥290 MPa (annealed), which can be further increased to approximately 400 MPa after cold working. - Yield Strength: ≥70 MPa (annealed), reaching approximately 200 MPa after cold rolling.
- Elongation: ≥45% (annealed), exhibiting good plasticity and suitable for forming processes such as stamping and bending.
- Hardness: Approximately 55 HRB (annealed), adjustable through work hardening.
Characteristics and Advantages of ASTM B111 C23000 Polished Copper Pipe
- Corrosion Resistance: Excellent corrosion resistance in freshwater and atmospheric environments, suitable for pipes, valves, and other components.
- Electrical and Thermal Conductivity: Electrical conductivity is approximately 28% IACS, making it suitable for electrical connectors.
- Weldability and Processability: Easy to braze and solder, with good machinability.
C23000 brass, with its balanced mechanical properties and chemical stability, is a common material of choice in the industrial sector, particularly for applications requiring a balance between strength and formability.

Packaging and shipping
GNEE offers professional packaging for exported copper pipes. First, we apply anti-rust oil and plastic film to prevent oxidation. Then, we securely strap with steel straps and add corner protectors. Finally, we place the pipes on wooden pallets and reinforce them with iron or wooden boxes, ensuring they are moisture-proof and impact-resistant during ocean transport, while facilitating easy loading and unloading. All packaging meets export standards.
