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.
