Copper C12200 tubes, also known as phosphorus-deoxidized copper (Cu-DHP), are widely used in plumbing, HVAC, refrigeration, and industrial applications. This grade of copper is known for its excellent corrosion resistance, high thermal conductivity, and superior weldability. Due to its balanced mechanical and physical properties, Copper C12200 is one of the most preferred materials for fluid and gas transmission systems.
What is Copper C12200?
Copper C12200 is a high-purity copper alloy containing a small amount of phosphorus. The phosphorus acts as a deoxidizing agent during manufacturing, which improves weldability and reduces the risk of hydrogen embrittlement.
Chemical Composition:
Copper (Cu): 99.9% minimum
Phosphorus (P): 0.015–0.040%
This composition provides a strong combination of corrosion resistance, ductility, and excellent thermal performance.
Key Features of Copper C12200 Tubes
1. Excellent Corrosion Resistance
Copper C12200 tubes resist corrosion in water, steam, and non-oxidizing acids, making them ideal for plumbing and industrial piping systems.
2. High Thermal Conductivity
Copper is known for its outstanding heat transfer capability, making C12200 tubes perfect for HVAC and refrigeration systems.
3. Good Weldability and Formability
The phosphorus content enhances weldability and allows easy fabrication, bending, and brazing.
4. Resistance to Hydrogen Embrittlement
Compared to oxygen-bearing copper grades, C12200 offers better resistance to hydrogen-related cracking.
5. Long Service Life
These tubes provide durability and reliable performance in both residential and industrial applications.
