C12000 vs. C12200 Phosphorus-Deoxidized Copper
| Comparison Dimension | C12000 (Low-Phosphorus Deoxidized Copper) | C12200 (High-Phosphorus Deoxidized Copper) |
|---|---|---|
| Common Name / Standard | DLP (Deoxidized Low Phosphorus) UNS C12000 / ASTM B124 | DHP (Deoxidized High Phosphorus) UNS C12200 / ASTM B124 |
| Phosphorus Content (P) | 0.004% – 0.012% | 0.015% – 0.040% |
| Oxygen Content (O) | Very low (typically < 50 ppm) | Very low (effectively deoxidized) |
| Electrical Conductivity | Very High (≥ 98% IACS) Close to pure copper (C11000). | Good (≥ 85% IACS) Reduced due to higher P content. |
| Thermal Conductivity | Very High (~350 W/(m·K)) | High (~250 W/(m·K)) |
| Key Feature / Mechanism | Minimal phosphorus for essential deoxidation only, maximizing conductivity. | Higher phosphorus ensures robust and stable deoxidation, enhancing other properties at the cost of some conductivity. |
| Hydrogen Embrittlement Risk | Eliminated (Very low oxygen content). | Eliminated (Effectively deoxidized). |
| Weldability & Brazability | Excellent for most methods (soldering, brazing, welding). | Superior (especially for brazing). Phosphorus acts as a self-fluxing agent in copper-phosphor brazing alloys. |
| Hot Workability | Good | Excellent (Phosphorus significantly improves hot ductility and extrusion performance). |
| Corrosion Resistance | Good (similar to pure copper). | Better (especially against dezincification in certain environments and for erosion-corrosion in water). |
| Typical Forms & Applications | Where high conductivity is critical: - High-efficiency busbars & conductors - Electrical contacts & terminals - Precision electronic components - Vacuum tube parts | Where fabrication and durability are critical: - Plumbing tubes & fittings (main use) - Heat exchanger tubes (ACR) - Medical gas piping (ASTM B819) - Roofing & flashing - General sheet metal work |
| Cost & Availability | Generally higher cost due to tighter process control. | Very common and cost-effective; the industry standard for many plumbing and general engineering applications. |
Choose C12000 (DLP) when: Your design demands the highest possible electrical or thermal conductivity in a safely deoxidized copper, such as in critical electrical power distribution, high-frequency applications, or precision instrument parts where performance loss must be minimized.
Choose C12200 (DHP) when: Your application is driven by fabrication needs, corrosion resistance, and overall economy. It is the default choice for plumbing, HVAC, general heat exchangers, and architectural applications where its excellent hot workability, superior brazability, and good overall performance offer the best balance.
