FAQ
| 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. |
| What tempers are available for C12000 tubing? Common tempers are annealed (soft, O60), drawn (hard, H58), and light-drawn (H55). Annealed offers maximum formability; drawn provides higher strength. |
| Can C12000 be used in oxygen service or medical gas systems? Yes, after proper cleaning and degreasing, C12000 tubes are widely used in medical gas (oxygen, nitrous oxide) and high-purity gas systems due to their cleanliness and non-permeability. |
| How does phosphorus affect conductivity in C12000? 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. |
