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.
