What is TP1/C12000 copper?
C12000 phosphorus-deoxidized copper is a copper alloy that undergoes deoxidation treatment by adding trace amounts of phosphorus (0.004%–0.012%). Its unique composition design significantly improves welding and processing performance while retaining high electrical and thermal conductivity, making it a key material in industrial fields.

Key Distinctions from Other Common Coppers
vs. C11000 (ETP Copper - Electrolytic Tough Pitch):
C11000 contains oxygen (~0.04%). It is not recommended for welding or high-temperature reducing atmospheres (risk of hydrogen embrittlement). C12000 is preferred for welded applications.
vs. C12200 (Similar DHP Copper):
C12200 has a slightly higher phosphorus range. They are often considered interchangeable for many applications, but C12200 is more common for plumbing tube.
vs. C10100 / C10200 (Oxygen-Free Copper):
OF coppers have higher conductivity (101% IACS) and superior ductility. They are used for high-vacuum electronics and critical conductors. C12000 is more economical for general plumbing and heat exchangers.
FAQ
FAQ
Q: What tempers are available for C12000 tubing?
A: Common tempers are annealed (soft, O60), drawn (hard, H58), and light-drawn (H55). Annealed offers maximum formability; drawn provides higher strength.
Q: How does phosphorus affect conductivity in C12000?
A: The low residual phosphorus slightly reduces electrical conductivity (~85% IACS) compared to pure C11000 (~101% IACS), but it remains excellent for most thermal and electrical applications.
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.
