What is TP1/C12000 copper?
C12000 copper possesses excellent electrical and thermal conductivity due to its high-purity copper matrix. Furthermore, it exhibits good machinability, allowing for various cold and hot processing techniques such as forging, rolling, drawing, and stamping. This makes C12000 copper widely used in the manufacture of wires and cables, electronic components, automotive parts, HVAC, and refrigeration equipment. In addition to its superior physical properties, C12000 copper plates also exhibit good corrosion resistance, especially in humid environments and soil. This allows it to maintain stable performance even when exposed to harsh environments for extended periods.

Choose UNS C12000 (DLP - Low P) when:
High electrical or thermal conductivity is the TOP priority. Examples:
Electrical Busbars and high-efficiency windings.
Heat Exchanger tubes or components where maximum thermal transfer is critical.
Lightning Conductor systems.
The application involves high-temperature brazing or welding in an atmosphere that is NOT reducing (e.g., inert gas, vacuum, air).
You need superior cold working properties for severe forming (marginally better than C12200).
Choose UNS C12200 (DHP - High P) when:
The application involves plumbing, hydronic heating, refrigeration, or fuel/gas lines. This is the standard, most widely used copper water tube alloy globally.
Safety against hydrogen embrittlement is paramount. This includes:
Any service in a reducing atmosphere (e.g., components for hydrogen or synthesis gas systems).
Annealing or brazing in a furnace with a reducing atmosphere.
Cost-effectiveness is important for standard applications not requiring peak conductivity. C12200 is more commonly produced and often more readily available.
Good overall formability, weldability, and brazability are sufficient.
