What is C12000 copper?
Red copper is a common name for pure copper, named for its purplish-red color after oxidation. It has a high purity, typically exceeding 99.9%, and possesses excellent electrical and thermal conductivity, as well as corrosion resistance. Red copper also exhibits excellent ductility, making it easy to process into various shapes, including pipes, plates, and wires. TP1/C12000 is a grade of red copper, indicating the presence of trace amounts of specific elements to improve certain properties while maintaining high purity.

C12000 vs C10100
| Feature | UNS C12000 | UNS C10100 |
|---|---|---|
| Common Name | Phosphorus Deoxidized, Low P (DLP) | Oxygen-Free Electronic (OFE) |
| Purity Level | High Purity (≥99.90% Cu) | Ultra-High Purity (≥99.99% Cu) |
| Key Characteristic | Deoxidized with Phosphorus | No deoxidizers, ultra-low oxygen (<0.0005%) |
| Electrical Conductivity | Very High (~100% IACS) | Maximum (>101% IACS) |
| Thermal Conductivity | Very High | Highest |
| Ductility & Formability | Excellent | Exceptional (best among coppers) |
| Weldability & Brazability | Excellent (forgiving in air) | Excellent (requires careful atmosphere control) |
| Resistance to Hydrogen Embrittlement | Poor (in reducing atmospheres) | Excellent (immune, no oxide to react) |
| Annealability | Good | Superior, more uniform |
| Relative Cost | Premium | Premium+ (Most Expensive) |
| Typical Applications | High-conductivity busbars, heat exchangers, welded tubing | Semiconductor parts, vacuum tubes, RF components, high-performance targets |
Choose C10100 (OFE) when your priority is:
Ultimate Conductivity & Purity: For critical electronic components (e.g., waveguide cavities, accelerator parts, high-power RF conductors).
Extreme Environment Stability: For service in high-vacuum, high-temperature (>400°C), or hydrogen-rich atmospheres where any outgassing or embrittlement is unacceptable.
Superior Cold Workability: For applications requiring the most severe deep drawing or forming without annealing (e.g., specialized seals, diaphragms).
Superior Annealability: For applications requiring a perfectly uniform, clean, and bright annealed finish.
Choose C12000 (DLP) when your priority is:
Excellent Conductivity at a Lower Cost: For high-performance electrical/thermal applications where C10100's marginal performance gain is not cost-justified (e.g., premium busbars, heat exchangers).
Easier Fabrication Joining: For welding and brazing in standard shop environments without stringent atmosphere control.
General High-Performance Applications: Where top-tier conductivity is needed, but the ultra-pure, extreme-environment capabilities of OFE copper are unnecessary.
Availability & Standardization: It is more commonly stocked and specified for industrial (non-electronic) high-conductivity uses.

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.
| Nominal Size (inches) | Type K | Type L | Type M |

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.
