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 (401W/mcdotpK) and corrosion resistance in chloride-rich environments.
