What is TP1/C12000 copper?
Pure copper has a high electrical and thermal conductivity. Copper may readily form alloys. Grade C12000 copper possesses 95 percent IACS conductivity, minimal residual phosphorus, and strong embrittlement resistance. The machinability of Copper Grade C12000 Pipes is 20 Percent. Grade C12000 copper pipes may be annealed at temperatures ranging from 372°C to 649°C (700°F to 1200°F). Copper C12000 Pipe is used in bus bars and electromechanical hardware connections. Regular wall thickness sizes range from 1/8 inch to 12 inch diameters, while exceptionally strong wall thickness sizes range from 1/8 inch to 10 inch. Copper Grade C12000 pipe has a typical length of 12 feet. Copper C12000 pipe is appropriate for plumbing, boiler feed lines, refrigeration, and other related applications.
Material Properties:
Superior electrical and thermal conductivity compared to TP2 phosphorus deoxidized copper, due to its lower residual phosphorus content.
Good weldability and formability; less prone to cracking during cold bending.
Strong stability in reducing atmospheres, preventing hydrogen embrittlement.
Applications:
Primarily used in the following scenarios:
Energy Transmission Systems: Fluid transmission components such as gasoline or gas delivery pipes, drainage pipes, and condenser pipes.
Heat Exchange Equipment: Core components such as condenser tubes, evaporator tubes, and heat exchanger tubes.
Transportation Equipment: Train car parts, gasoline or gas delivery pipes, drainage pipes, condenser pipes, mine casings, condensers, evaporators, and heat exchangers.

C12000 vs C10200
| Feature | UNS C12000 | UNS C10200 |
|---|---|---|
| Common Name | Phosphorus Deoxidized, Low Residual P (DLP) | Oxygen-Free Copper (OF) |
| Key Composition | Cu ≥99.90%, P: 0.004-0.012% | Cu ≥99.95%, O ≤0.0005% |
| Oxygen Content | Very Low | Extremely Low (Virtually Zero) |
| Deoxidizer | Phosphorus | None (Process-controlled) |
| Electrical Conductivity | Very High (~100% IACS) | Highest (~101%+ IACS) |
| Thermal Conductivity | Very High | Slightly Higher |
| Formability & Ductility | Excellent | Superior (especially in annealed state) |
| Weldability & Brazability | Excellent (due to P deoxidation) | Excellent (requires inert atmosphere) |
| Resistance to Hydrogen Embrittlement | Poor (in reducing atmospheres) | Very Good (no Cu₂O to react) |
| Typical Applications | High-conductivity busbars, heat exchangers, tubing | High-vacuum electronics, glass-metal seals, waveguides, sputtering targets |
Choose C10200 (Oxygen-Free Copper) when your priority is:
Maximum Purity & Conductivity: For critical electrical/electronic components (e.g., waveguides, semiconductor parts).
High-Temperature in Hydrogen: For service in reducing atmospheres (e.g., hydrogen furnaces, brazing atmospheres) where hydrogen embrittlement is a risk.
Superior Ductility & Forming: For severe cold working and deep drawing applications.
High-Vacuum or Sealing Applications: Where outgassing or oxidation at high temperatures must be absolutely minimized (e.g., glass-metal seals, accelerator parts).
Choose C12000 (Phosphorus Deoxidized Copper) when your priority is:
Excellent Conductivity at Lower Cost: For high-performance busbars, electrical conductors, and heat exchangers where C10200's marginal gain isn't justified.
Easier Joining in Air: Its deoxidized nature makes it very forgiving for welding and brazing in standard shop environments.
General High-Conductivity Applications: Where hydrogen embrittlement is not a concern (e.g., standard electrical components, non-reducing atmosphere heat transfer).
Good Balance of Performance and Practical Fabrication.
