Oxygen Free Copper
High purity oxygen-free copper with excellent conductivity, low oxygen content and superior performance for semiconductor, electrical and vacuum applications.
High quality copper tubes supplied in seamless and customized forms for heat exchangers, refrigeration, plumbing and industrial applications.
Copper tube is a tubular copper product manufactured from pure copper or copper alloy materials. It provides excellent thermal conductivity, corrosion resistance, ductility and long service life.
Due to its outstanding heat transfer capability and reliability, copper tube is widely used in refrigeration systems, air conditioning equipment, heat exchangers, plumbing systems and industrial applications.
Common copper tube materials include C10100 oxygen free copper, C10200 oxygen free copper and C12200 phosphorus deoxidized copper, which are selected according to application requirements.
Different copper grades provide different performance characteristics for electrical, thermal and industrial applications.
| Grade | Material Type | Main Features |
|---|---|---|
| C10100 | Oxygen Free Copper | High purity and excellent conductivity |
| C10200 | Oxygen Free Copper | Low oxygen content and high reliability |
| C11000 | Electrolytic Copper | Excellent electrical and thermal conductivity |
| C12200 | Phosphorus Deoxidized Copper | Excellent welding performance and corrosion resistance |
| C44300 | Admiralty Brass | Good corrosion resistance for heat exchangers |
Pure copper tubes contain high copper content, while alloy copper tubes add elements such as zinc or phosphorus to improve strength and application performance.

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
