What is JIS H3300 C1220T Copper Tube?
JIS H3300 C1220T is a phosphorus-deoxidized copper alloy containing a minimum of 99.90% copper (Cu+Ag) and controlled phosphorus content. It is internationally recognized as Cu-DHP (Copper Deoxidized High Phosphorus).
The addition of phosphorus removes residual oxygen from the copper, significantly improving:
- Weldability
- Brazing performance
- Corrosion resistance
- Resistance to hydrogen embrittlement
- Long-term reliability in refrigeration systems
Compared with oxygen-bearing copper grades such as C1100, C1220T is the preferred material for refrigeration and air-conditioning tubing.
