JIS H3300 C1220T Oxygen-Free Copper Alloy Seamless Tube – Superior Heat Transfer & Corrosion Resistance for Heat Exchangers

1. Product Overview​​

​​JIS H3300 C1220T Seamless Copper Alloy Tubes​​ are engineered for high-efficiency heat transfer in boilers, condensers, and chemical processing systems. Manufactured under ​​JIS H3300​​ standards, these oxygen-free copper (OFC) tubes offer unmatched thermal conductivity ($401\text{W/mcdotpK}$) and corrosion resistance in chloride-rich environments.

​​2. Material & Chemical Composition​​

• ​​Material​​: Phosphorus-deoxidized copper (99.9% Cu min, 0.15–0.40% P).
• ​​Key Chemical Properties​​:

​​3. Mechanical Properties​​

​​4. Key Features & Advantages​​

• ​​Ultra-High Thermal Conductivity​​: 90% IACS (International Annealed Copper Standard).
• ​​Seamless Design​​: No welds, ensuring leak-proof performance under high pressure (up to 30 MPa).
• ​​Easy Fabrication​​: Excellent flaring, welding, and bending properties.
• ​​Certified Quality​​: Complies with ​​JIS H3300, ASTM B88, and EN 10216​​.

​​5. Applications​​

• ​​HVAC Systems​​: Condensers, evaporators.
• ​​Chemical Processing​​: Acid/alkali heat exchangers.
