JIS H3300 C1220T Red Copper Seamless Tube High-Percision Heat Exchanger Tube
JIS H 3300 C1220T is the Japanese standard specification for hard-drawn, phosphorus-deoxidized copper tubing. It covers dimensions, tolerances, mechanical properties, and testing methods. It is the workhorse material for high-quality plumbing and heating systems in Japan and many parts of Asia, with direct equivalents used across Europe and the Americas. Its "T" (hard) temper provides high strength for straight runs, while its C1220 composition ensures excellent joinability and corrosion resistance.
Material & Metallurgical Features of JIS H3300 C1220T Red Copper Tube
| Feature | Description |
|---|---|
| High Purity | Minimum 99.90% copper content. |
| Deoxidized | Contains 0.015–0.040% phosphorus to eliminate oxygen, preventing embrittlement during welding/brazing. |
| "Red Copper" Color | Distinctive reddish metallic appearance (vs. yellow brass). |
| Non-Arsenical | Unlike condenser tube alloys (e.g., Admiralty Brass), C1220 is arsenic-free, making it safe for potable water. |
Mechanical & Physical Features of JIS H3300 C1220T Red Copper Tube
| Feature | Description |
|---|---|
| High Strength (Hard Temper) | Tensile strength ≥315 MPa. Ideal for rigid, straight piping runs that require minimal deflection. |
| Good Ductility | Elongation ≥30% allows for some bending (with proper tools) and resistance to rupture. |
| Excellent Thermal Conductivity | ~350 W/(m·K). Highly efficient for heat transfer in heating systems. |
| Superior Electrical Conductivity | ~85% IACS (slightly lower than OFC due to phosphorus). |
| Bacteriostatic Surface | Copper ions inhibit the growth of bacteria, fungi, and viruses, enhancing water quality. |

Understanding the difference between ASTM B111 and JIS H3300 tubes is crucial for specifying materials in projects with international standards. The core difference is not primarily about material, but about the intended application and the scope of the standard.
1. PURPOSE
ASTM B111: Heat exchanger/condenser tubes (specialized for heat transfer)
JIS H3300: General-purpose pipes/tubes (plumbing, water supply, heating)
2. INDUSTRY USE
ASTM B111: Power plants, ships, desalination plants, chemical industry
JIS H3300: Construction, plumbing, HVAC, general manufacturing
3. KEY TESTS
ASTM B111: Ammonia stress corrosion test (mandatory for certain alloys), tube expansion tests
JIS H3300: Standard mechanical tests (tensile, flattening), hydrostatic/eddy current tests
