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.
