What is TP1/C12000 copper?
TP1 phosphorus-deoxidized copper alloy is a high-purity copper alloy containing phosphorus for deoxidation, primarily used in the power, electrical, electronic, and communications industries. Due to its excellent electrical and thermal conductivity and corrosion resistance, TP1 phosphorus-deoxidized copper alloy is widely used in the manufacture of various electrical components, heat exchangers, and other industrial equipment.
Main Application Areas of TP1 Copper Tubes
*Refrigeration and Air Conditioning Industry: This is one of the innovative application markets for copper tubes. Because of copper's good thermal conductivity, ease of bending and connection, and resistance to refrigerant corrosion, it is an ideal tube material for connecting compressors, condensers, and evaporators in refrigerators, air conditioners, and other equipment. The good heat resistance of TP1 copper tubes also makes them suitable for the internal operating temperatures of air conditioning systems.
*Heat Exchangers and Radiators: In heat exchange equipment in the power, chemical, and shipbuilding industries, copper tubes are used as heat transfer elements. They can efficiently transfer heat between fluids. Copper tubes are also commonly used in automotive radiators and power plant condensers.
*Water and Gas Supply Systems: Copper pipes are antibacterial, corrosion-resistant, and have a long service life, making them the preferred material for hot and cold water pipes and gas pipelines in high-end buildings. Their smooth inner walls are less prone to scaling, ensuring smooth water flow.
*Industrial Piping: In industries such as chemical, food, and pharmaceutical, copper pipes are used to transport media with special requirements for pipe materials due to their corrosion resistance and non-toxicity.
*Other Industrial Applications: Copper pipes are also used in the manufacture of bearings, bushings, hydraulic system piping, and various electrical components requiring high electrical and thermal conductivity.

FAQ
| What's the difference between C11000 (ETP) and C12000 (DHP)? C11000 (ETP – Electrolytic Tough Pitch) contains oxygen and may suffer from hydrogen embrittlement in reducing atmospheres. C12000 is deoxidized with phosphorus, making it suitable for brazing, welding, and high-temperature applications without embrittlement risk. |
| Can C12000 copper be welded or brazed easily? Yes, C12000 is highly weldable and brazeable due to its deoxidized nature. Autogenous welding and brazing can be performed without flux when joining copper-to-copper. |
| What are the main applications of C12000 copper tubes? It's widely used in HVAC/R (heat exchangers, condensers), plumbing, medical gas systems, industrial fluid lines, and electrical busbars. |
| Does C12000 copper corrode in water systems? It has excellent corrosion resistance in clean, non-aggressive water. However, like all copper, it can be affected by acidic water, high-velocity flow, or certain chemicals (e.g., ammonia, sulfides). |
| Is C12000 suitable for underground water lines? Yes, especially when using Type K thick-walled tubing for burial. Its corrosion resistance and strength make it a durable choice for direct burial when soil conditions are non-aggressive. |
| What standards cover C12000 copper tubes? ASTM B75 (seamless), B280 (ACR tubes), EN 12735-1, and JIS H3300 are key standards for tubing. ASTM B152 covers sheet/plate forms. |
| What tempers are available for C12000 tubing? Common tempers are annealed (soft, O60), drawn (hard, H58), and light-drawn (H55). Annealed offers maximum formability; drawn provides higher strength. |
