What is the C12000/TP1 Copper Pipe?
C12000 copper pipe has very excellent electrical and thermal conductivity with its high purity copper matrix. In addition, it has good processing properties and goes well with various cold and hot working processes, such as forging, rolling, drawing and stamping. This makes C12000 copper pipes widely used in the manufacturing of wires, cables, electronic components, automotive parts, HVAC and refrigeration equipment and other fields. In addition to its excellent physical properties, C12000 copper pipe also has remarkable corrosion resistance, especially in humid environment and soil. This allows it to maintain stable performance in situations where prolonged exposure to harsh environments is required.

Why C12000/TP1 Copper Pipe is Suitable for Air Conditioning
Best Heat Transfer – Highest thermal conductivity among practical metals for efficient cooling.
Easy to Work With – Soft temper allows easy bending; solders/brazes perfectly for leak-proof joints.
Corrosion Resistant – Naturally withstands moisture, weather, and refrigerants for decades.
Strong & Durable – Handles high system pressures and resists cracking under vibration/cycling.
Clean & Safe – Antimicrobial surface inhibits mold/bacteria growth inside tubing.
differences between C12000/TP1 and TP2/C12200.
| Feature | C12000 / TP1 (Low-Residual Phosphorus) | TP2 / C12200 (Standard Phosphorus) |
|---|---|---|
| 1. Phosphorus (P) Content | Low: 0.004% - 0.012% | Higher: 0.015% - 0.040% |
| 2. Primary Advantage | Higher Thermal & Electrical Conductivity (closer to pure copper). | Superior Brazing/Soldering Characteristics and excellent general corrosion resistance. |
| 3. Best Application | High-efficiency Heat Exchangers where maximum heat transfer is critical. | Plumbing & General Refrigeration Tubing where reliable joining and overall durability are key. |
| 4. Key Trade-off | Slightly higher cost; marginally less oxide-free surface for brazing vs. TP2. | Slightly lower conductivity due to higher phosphorus impurity. |
Use C12000/TP1 when your priority is maximum thermal performance (e.g., high-end condenser/evaporator coils).
Use TP2/C12200 for most standard applications (water pipes, standard AC lines) where its excellent brazeability and proven reliability are ideal.

FAQ
Q1: What is the main advantage of using C12000/TP1 over other copper types in air conditioners?
A: Its primary advantage is superior thermal conductivity. Due to its lower phosphorus content, C12000/TP1 conducts heat more efficiently than the more common TP2/C12200, leading to potentially higher system efficiency and faster heat exchange in condensers and evaporators.
Q2: Is C12000/TP1 suitable for all parts of an AC refrigerant circuit?
A: Yes, it is excellent for the entire circuit, including connecting lines, evaporator coils, and condenser coils. Its combination of strength, formability, and corrosion resistance makes it a comprehensive solution.
Q3: Is it harder to braze or solder than standard copper tubes like TP2?
A: No, it is generally very easy to braze. The phosphorus acts as an effective deoxidizer, preventing oxide formation during heating. While TP2 is often cited as having the "best" brazing characteristics, C12000/TP1 provides excellent, reliable, and leak-free joints standard in the industry.
Q4: Why isn't C12000/TP1 the most common copper if it has better conductivity?
A: Cost vs. Performance Requirement. TP2/C12200 offers outstanding brazeability, corrosion resistance, and good enough conductivity for the vast majority of standard applications at a competitive cost. C12000/TP1 is typically specified for high-performance or premium systems where maximizing efficiency justifies a slightly higher material cost.
Q5: How does its durability compare to TP2 in AC systems?
A: Durability is equally excellent. Both alloys offer superb corrosion resistance against moisture, refrigerants, and atmospheric conditions. The inherent strength of copper ensures both can withstand system pressures and thermal cycling for the long operational life of an AC unit.
Our factory
Our factory specializes in the research and development, production, and quality control of high-quality copper tubes. Equipped with modern precision rolling and drawing production lines, we strictly adhere to multiple international standards, including ASTM B280 (Seamless Copper Tube for Air Conditioning and Refrigeration Field), ASTM B88 (Seamless Copper Water Tube), and ASTM B75 (Seamless Copper Tube). We professionally manufacture seamless copper tubes suitable for air conditioning and refrigeration, building water systems, and industrial heat exchange applications. Through stringent processes such as eddy current testing and spectral analysis, we ensure that every copper tube delivers excellent thermal conductivity, sealing performance, and corrosion resistance. We provide global customers with reliable, internationally compliant products and customized solutions.
Copper product packaging
For copper coiled tubes, we adopt a customized coil packaging solution: each coil is wound around a high-strength industrial paper core or plastic winding core for support, entirely wrapped with vapor corrosion inhibitor (VCI) film and sealed at the ends. It is then placed into a pressure-resistant corrugated cardboard cylinder or a custom carton, and finally secured on an IPPC-standard wooden pallet. With edge protectors and steel strapping reinforcement, we ensure the coil maintains its shape, remains protected against moisture and impact, and meets international shipping requirements.
