What is JIS H3300 C1220T Copper Tube?
C1220T is a phosphorus-deoxidized copper (Cu-DHP) grade containing ≥99.90% copper with controlled phosphorus content (0.015–0.040%). The phosphorus improves weldability and eliminates hydrogen embrittlement risk, making it ideal for refrigeration and air-conditioning systems.
Unlike oxygen-bearing copper (C1100), C1220T offers superior brazing performance and enhanced corrosion resistance in HVAC applications.
Chemical Composition of C1220T Copper Tube
| Element | Content (%) |
|---|---|
| Cu + Ag | ≥ 99.90 |
| Phosphorus (P) | 0.015 – 0.040 |
| Impurities | ≤ 0.10 |
The low oxygen content ensures excellent reliability during high-temperature brazing.
Mechanical Properties (Solution Annealed)
| Temper | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|
| O (Soft) | ≥ 205 | ≥ 40 |
| 1/2H | ≥ 240 | ≥ 10 |
| H (Hard) | ≥ 295 | ≥ 3 |
C1220T combines high ductility with sufficient mechanical strength for bending and forming.
