What is C12000 ?
Cu-DLP is a phosphorus-deoxidized copper with a limited, medium amount of residual Phosphorus. It has a good electrical conductivity and excellent welding and soldering properties. It can be formed excellent, either hot or cold.
UNS C12000 copper has 95% IACS conductivity, low residual phosphorus, and high embrittlement resistance. It has a good electrical conductivity and excellent welding and soldering properties. It can be formed excellent, either hot or cold.
C12000 Copper Tube – Phosphorized Copper (DHP Copper)
C12000 Copper (also known as Phosphorized Copper – DHP Copper) is a high-purity copper alloy with excellent corrosion resistance, high thermal and electrical conductivity, and good formability. It is commonly used in heat exchangers, plumbing, refrigeration, and industrial piping systems.

FAQ
Q: Can C12000 copper be welded or brazed easily?
A: 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.
Q: What are the main applications of C12000 copper tubes?
A: It's widely used in HVAC/R (heat exchangers, condensers), plumbing, medical gas systems, industrial fluid lines, and electrical busbars.
Q: Does C12000 copper corrode in water systems?
A: 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).
Q: Is C12000 suitable for underground water lines?
A: 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.
Q: What is the difference between TP1 and TU1 copper?
A: TP1 and TU1 are both oxygen-free coppers, but they belong to different metallurgical categories: TP1 (C12000): Phosphorus-deoxidized copper (DHP). Contains trace phosphorus to remove oxygen. Suitable for welding/brazing and offers good conductivity.
TU1 (C10100): Oxygen-free electronic copper (OF). Contains no deoxidizers (virtually 0% oxygen and no phosphorus). Offers the highest purity (≥99.99% Cu) and optimal electrical/thermal conductivity (~101% IACS). Used in high-vacuum electronics, superconducting applications, and high-frequency conductors.
Key takeaway: TP1 is a deoxidized copper for general engineering, while TU1 is ultra-pure oxygen-free copper for high-end electronic and specialized applications.

Our factory
Our factory is built for precision and scale in producing copper rods, tubes, plates, bars, wires, and strips. We operate advanced equipment such as upward continuous casting systems for oxygen-free copper rods, CNC-controlled pilger mills for seamless tubes, and automated strip rolling lines with real-time thickness monitoring. All products are manufactured to meet ASTM, DIN, and customer-specific standards, with process control at every stage. Our quality assurance includes metallographic analysis, conductivity testing, and surface quality inspection via optical comparators. From raw material to finished product, we ensure consistency, performance, and on-time delivery for industrial and OEM partners globally.
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.
