C12200 Phosphorus Deoxidized Copper

-- Steady & Reliable Manufacturer --

The Industry Standard for Technical Copper

C12200, known internationally as Cu-DHP (Copper-Deoxidized High Phosphorus), is the most widely used copper grade for engineering, HVAC, and industrial applications. Unlike pure electrolytic copper (C11000), which can suffer from "hydrogen embrittlement" when heated or welded, C12200 is intentionally deoxidized with phosphorus. This process removes the oxygen content, making the material exceptionally stable during brazing and welding operations. With a copper content of at least 99.9%, C12200 retains most of the excellent thermal and electrical conductivity of pure copper while gaining the mechanical reliability required for pressurized systems. At Zhejiang Jingliang, we specialize in the high-precision processing of C12200, ensuring that the phosphorus content is strictly controlled within the 0.015% to 0.040% range. This precise balance is what gives our tubes their world-renowned ductility, allowing them to be bent, flared, and expanded without the risk of stress cracking.

The choice of C12200 is driven by the need for longevity in modern infrastructure. Because it is phosphorus-deoxidized, this grade is much less susceptible to atmospheric corrosion and internal pitting compared to other alloys. This makes it the only logical choice for refrigerant lines, medical gas systems, and high-end plumbing. Our C12200 tubes undergo a bright annealing process in a vacuum or controlled-atmosphere furnace, which results in a mirror-like finish and a completely scale-free internal surface. This is critical for the HVACR industry, where internal cleanliness is the number one factor in preventing compressor failure. By understanding the molecular science of C12200, we are able to produce copper products that meet the highest global standards, providing a material foundation that engineers can trust for their most critical thermal management and fluid transport designs.

Applications in Precision Engineering

C12200 is the "workhorse" material of several multi-billion dollar industries. Its primary home is in the HVACR sector, where it is used to manufacture everything from household air conditioners to industrial-scale chillers. Because of its excellent brazing properties, it is the standard material for heat exchanger fins and tubes. In the construction industry, it is used for high-pressure water and gas distribution systems, as well as for solar thermal absorbers. Its resistance to hydrogen embrittlement makes it essential for any application involving welding or high-temperature brazing, such as in the assembly of large-scale condensers and evaporators. In the automotive industry, C12200 is used for oil coolers and hydraulic lines. It is also the preferred material for medical gas systems in hospitals, as it can be thoroughly degreased and maintain its cleanliness throughout the installation process. Essentially, wherever a reliable, ductile, and thermally efficient pipe is needed, C12200 is the material of choice.

Advantages of Choosing C12200 Grade

The main advantage of C12200 is its "brazeability." In industrial manufacturing, speed and reliability are key; C12200 allows for fast, clean joints that are stronger than the pipe itself. Another major benefit is its exceptional ductility. Our C12200 tubes can be expanded or bent to tight radii without losing wall thickness integrity, which is vital for the manufacturing of complex heat exchanger coils. From a durability standpoint, C12200 offers superior resistance to "season cracking" and other forms of environmental stress. For the end-user, this translates to a piping system that can last 50+ years with zero maintenance. Furthermore, C12200 is 100% recyclable without any loss of properties, making it an environmentally responsible choice for "green" building projects. At Jingliang, our specialized grain-size control during the drawing process ensures that our C12200 tubing has a uniform mechanical profile, resulting in consistent performance across millions of meters of production.

Payment, Supply, and Compliance

As a primary manufacturer, we supply C12200 in all formats: LWC coils, pancake coils, and straight lengths. We maintain a large inventory of raw copper cathode to ensure we can meet large orders despite market fluctuations. We accept T/T, L/C, and offer credit-based terms for our long-term OEM partners. Every shipment of C12200 from our factory is accompanied by a Mill Test Certificate (MTR) according to EN 10204 3.1, providing a full chemical and mechanical breakdown of the batch. We also provide compliance certificates for RoHS and REACH, ensuring that our material is safe for use in all global markets. Our logistics team is expert at coordinating multi-modal transport to ensure that your factory receives its C12200 supply just-in-time, minimizing your warehousing costs and maximizing your production throughput.

  • Q: Why not use C11000 (ETP) copper for HVAC?
  • A: C11000 contains small amounts of oxygen. When you braze it, the hydrogen in the torch flame can react with that oxygen to form steam inside the copper, causing it to crack (hydrogen embrittlement). C12200 is deoxidized to prevent this exact problem.
  • Q: Is C12200 lead-free?
  • A: Yes, our C12200 copper is 100% lead-free and safe for potable water and medical applications.
  • Q: What is the maximum pressure a C12200 pipe can handle?
  • A: This depends on the diameter and wall thickness. However, C12200 is rated for the high pressures of R410A and CO2 refrigerants when the appropriate wall thickness is selected.
