Copper Alloy Tube JIS H 3330 C1220T Copper Nickel Seamless Condenser Tubes
What is JIS H 3330 C1220T tube?
JIS H 3330 C1220T refers to a phosphorus-deoxidized copper tube standard specified by the Japanese Industrial Standards (JIS).
Key Features of JIS H 3330 C1220T Tube:
1. Material:
- C1220 (Phosphorus-Deoxidized Copper, DHP Copper)
- Contains a small amount of phosphorus (0.015–0.040%) for deoxidation, improving weldability and resistance to embrittlement.
- High thermal and electrical conductivity (though slightly lower than pure copper due to phosphorus content).
- Excellent corrosion resistance, especially in water and steam applications.
| Grade | Chemical Composition% | Tensile Strength |
| Cu | P | N/mm2 |
| C1220T | 99.9 | 0.015 | 315 |
| | 0.040 | |
2. Standard:
- JIS H 3330 covers seamless copper and copper alloy tubes for general piping.
3. Applications:
- Plumbing & HVAC systems (water supply, heating, refrigeration).
- Gas distribution, medical gas systems, and industrial piping.
- Often used where brazing or welding** is required.
4. Comparable Standards:
- ASTM B68 (C12200) – U.S. equivalent.
- EN 1057 (CW024A) – European equivalent.
