What is TP1/C12000 copper?
TP1/C12000, also known as phosphorus-deoxidized copper, has a standard chemical composition consisting of copper and phosphorus, with the balance being zinc. The addition of phosphorus primarily serves to enhance deoxidation, thereby improving the material's weldability and corrosion resistance. This copper alloy is widely used in the construction industry, shipbuilding, and automotive parts manufacturing. Its high electrical conductivity, good ductility, and excellent corrosion resistance make TP1 copper irreplaceable in these fields.
Chemical Composition:
Copper (Cu): 99.90%
Lead (Pb): 0.004 – 0.012%
Mechanical Properties
Tensile Strength: 215~345 MPa (215~275 MPa for tubes, 245~345 MPa for plates/bars).
Elongation: ≥8% (plates/bars), tube elongation ≥25%.
Hardness: 55~120 HV (55~100 HV for tubes, 75~120 HV for plates/bars).
It combines moderate strength and ductility to meet complex processing requirements.

C12000 copper vs. C12200 copper
| Feature | UNS C12000 (CDA 120) | UNS C12200 (CDA 122) |
|---|---|---|
| Common Name | Phosphorus Deoxidized, Low Residual P (DLP) | Phosphorus Deoxidized, High Residual P (DHP) |
| Primary Standard | ASTM B152, B124 | ASTM B152, B124 |
| ISO Designation | Cu-DLP | Cu-DHP |
| EN Designation | CW024A | CW024C |
| JIS Designation | C1201 | C1220 |
| Nominal Composition | 99.90% Cu min. | 99.90% Cu min. |
| Key Difference | Low Phosphorus (0.004 - 0.012%) | Higher Phosphorus (0.015 - 0.040%) |
| Electrical Conductivity | Very High (~100% IACS) | Good, but lower (~85% IACS) |
| Thermal Conductivity | Very High (~390 W/m·K) | Good (~340 W/m·K) |
| Resistance to Hydrogen Embrittlement | Poor | Excellent |
| Weldability & Brazability | Excellent (low P helps flow) | Excellent (P acts as a deoxidizer) |
| Soft Soldering | Excellent | Excellent |
| Typical Forms | Tube, pipe, sheet, plate, busbar | Tube, pipe (dominant), sheet, plate |
| Relative Cost | Slightly higher | Standard, most common |
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.
