What is C12000 copper?
The main component of pure copper is copper, typically exceeding 99.90%. High-purity copper endows the material with excellent electrical and thermal conductivity, second only to silver. The face-centered cubic crystal structure of pure copper gives it excellent plasticity, allowing for hot and cold pressure processing to create various shapes of tubes, plates, and wires.
TP1/C12000 is a type of phosphorus-deoxidized copper. During copper smelting, trace amounts of phosphorus are added as a deoxidizer to remove oxygen from the molten copper, improving its toughness and corrosion resistance. Compared to pure copper, TP1/C12000 pure copper has a higher recrystallization temperature, meaning it maintains good strength and shape stability at higher temperatures, and its resistance to high-temperature oxidation is also enhanced. The silver element further improves its creep resistance, making it less prone to plastic deformation under prolonged heat and stress. TP1/C12000 pure copper is particularly suitable for manufacturing parts that operate in high-temperature environments.

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 |
How to Choose
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.

Dimensional Range Table
In plumbing and HVAC standards, copper tubing is commonly classified into three main types based on wall thickness: Type K, Type L, and Type M.
Type K: Has the thickest wall. It is the strongest and most durable, primarily used for underground burial, high-pressure applications, and where the highest level of protection is required.
Type L: Has a medium wall thickness. It is the most common and versatile type, widely used for residential and commercial water supply lines (hot and cold) and for many HVAC applications.
Type M: Has the thinnest wall. It is suitable for above-ground, low-pressure residential water supply lines and some drainage applications, offering a cost-effective solution where conditions allow.
The outside diameter (OD) is the same for all three types within a given nominal size. The difference lies in the inner diameter (ID), which decreases as the wall gets thicker.

Copper product packaging
Our copper product packaging always prioritizes safety protection and professional identification. Copper rods and profiles are securely bundled with steel straps and fixed on reinforced wooden pallets, with waterproof and moisture-proof film wrapped around the exterior. Copper tubes are equipped with protective caps on both ends and packaged in custom-designed cartons or wooden crates with internal cushioning materials. Copper plates and strips are interleaved with anti-rust paper and fully encapsulated in steel-edged crates. All packages are affixed with clear product labels, specifications, and moisture-proof tags. For high-purity copper materials or those with special application requirements (such as oxygen-free copper wires and high-end copper strips), we also offer professional nitrogen-filled sealed packaging to ensure complete oxygen isolation during transportation and storage, preventing oxidation and maintaining the optimal performance and surface condition of the materials.
