C12200/TP2 Phosphorus Deoxidized Copper Seamless Tube, 99.9% Cu for Heat Exchangers
Yuhong is a leading manufacturer and supplier of high-quality copper products. We focus on producing durable and efficient copper products that meet various global standards, including ASTM, JIS, DIN, and EN. Our C12200/TP2 copper seamless tubes are widely used in heat exchangers, condensers, and other thermal transfer systems across marine, power generation, and chemical industries.
C12200 Chemical Composition
| Element | Composition (%) |
| Copper (Cu)** | 99.9 (min) |
| Phosphorus (P) | 0.015 - 0.040 |
| Other Impurities | ≤ 0.03 |
Note: The high copper content ensures optimal thermal and electrical conductivity, while phosphorus eliminates oxygen, improving corrosion resistance and preventing hydrogen embrittlement.

Heat Treatment States and Explanations
C12200 tubes are available in multiple heat treatment states, each suited to specific applications:
-
Annealed (O):
- Fully soft for maximum ductility.
- Suitable for bending, forming, and welding.
- Commonly used in heat exchangers and condensers.
-
Half-Hard (H55):
- A balance between strength and ductility.
- Ideal for applications requiring moderate mechanical strength and some flexibility.
-
Hard (H80):
- Maximum strength with minimal elongation.
- Used in high-pressure systems and environments where wear resistance is critical.
Applications
1. Heat Exchangers and Condensers
2. Air Conditioning and Refrigeration Systems
3. Plumbing and Gas Distribution
4. Chemical Processing
5. Marine Applications
