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.
