What is C12000 copper?
Copper C12000 is a phosphorus-deoxidized copper with a limited, medium amount of residual Phosphorus. It has good electrical conductivity and excellent welding and soldering properties. It can be formed excellent, either hot or cold. Copper C12000 has 95 percent IACS conductivity, low residual phosphorus, and high embrittlement resistance. Forging of UNS C12000 copper can be performed at a temperature of about 760 to 871 degrees C (1400 to 1600 degrees F). Copper C12000 Tubes have good forgeability, low machinability, and excellent hot and cold working capacity.

FAQ
| What is TP1/C12000 copper? TP1/C12000 is a phosphorus-deoxidized copper alloy with very low residual phosphorus (0.004–0.012%). It's oxygen-free and offers excellent thermal/electrical conductivity along with good weldability and formability. |
| 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. |

Dimensional Range Table
In plumbing and HVAC standards, copper tubing is commonly classified into three main types based on wall thickness: Type K, Type L, and Type M.
Type K: Has the thickest wall. It is the strongest and most durable, primarily used for underground burial, high-pressure applications, and where the highest level of protection is required.
Type L: Has a medium wall thickness. It is the most common and versatile type, widely used for residential and commercial water supply lines (hot and cold) and for many HVAC applications.
Type M: Has the thinnest wall. It is suitable for above-ground, low-pressure residential water supply lines and some drainage applications, offering a cost-effective solution where conditions allow.
The outside diameter (OD) is the same for all three types within a given nominal size. The difference lies in the inner diameter (ID), which decreases as the wall gets thicker.
| Nominal Size (inches) | Type K | Type L | Type M |

Copper product packaging
Our copper product packaging always prioritizes safety protection and professional identification. Copper rods and profiles are securely bundled with steel straps and fixed on reinforced wooden pallets, with waterproof and moisture-proof film wrapped around the exterior. Copper tubes are equipped with protective caps on both ends and packaged in custom-designed cartons or wooden crates with internal cushioning materials. Copper plates and strips are interleaved with anti-rust paper and fully encapsulated in steel-edged crates. All packages are affixed with clear product labels, specifications, and moisture-proof tags. For high-purity copper materials or those with special application requirements (such as oxygen-free copper wires and high-end copper strips), we also offer professional nitrogen-filled sealed packaging to ensure complete oxygen isolation during transportation and storage, preventing oxidation and maintaining the optimal performance and surface condition of the materials.
