What is C12000 copper?
Copper C12000 is an alloy made from copper and other alloying elements. It contains up to 12% zinc, tin, nickel, iron, manganese, aluminium, and silicon. This combination creates a high-performance material that is both malleable and strong. Copper C12000 has numerous applications in engineering due to its impressive electrical properties and corrosion resistance. This alloy also provides excellent formability, making it highly desirable for use in components requiring precision machining.
Copper C12000 is a highly pure grade of copper popularly used in electrical and electronic applications. This grade has excellent mechanical and electrical properties, which makes it suitable for use in components such as connectors, bushings, motors, switches, and relays. It is also widely used as a conductor for data transmission due to its low impedance values. Copper C12000 offers superior corrosion resistance and is an ideal choice for many industrial applications where high levels of purity are required. Overall, this grade of copper provides great value with its versatile range of uses and robust properties.

C12000 - DHP Copper VS C12200 - DHP Copper
| Feature | C12000 - DHP Copper (Low Residual Phosphorus) | C12200 - DHP Copper (Standard / Higher Phosphorus) |
|---|---|---|
| Phosphorus (P) Content | Very Low: 0.004% to 0.012% | Higher & Controlled: 0.015% to 0.040% |
| Common Name / Standard | Phosphorus Deoxidized, Low Residual P (DHP) | Phosphorus Deoxidized, High Residual P (DHP). Often called "Phosphorized Copper" for plumbing. |
| Oxygen Content | Oxygen-Free (deoxidized by P) | Oxygen-Free (deoxidized by P) |
| Electrical Conductivity | Relatively High: ~85% to 90% IACS | Lower: ~80% to 85% IACS (P is a greater resistor) |
| Thermal Conductivity | Very Good | Good (slightly lower than C12000) |
| Key Property & Advantage | Optimized for a balance of good conductivity and excellent weldability. The minimal P maximizes conductivity within the weldable DHP family. | Optimized for superior corrosion resistance, particularly against dezincification in potable water systems. The higher P level provides this protection. |
| Weldability & Brazability | Excellent (Standard for DHP coppers) | Excellent (Standard for DHP coppers) |
| Primary Application Focus | Industrial Fabrication & HVACR: • Welded assemblies & heat exchangers • Refrigeration tubing & components • Applications where good conductivity and weldability are needed. |
Plumbing / Potable Water Systems: • Water tubes, pipes, and fittings (meets ASTM B88, B306). • The industry standard for modern plumbing. |
| Corrosion Resistance | Good general corrosion resistance. | Superior, specifically for water. The higher phosphorus content inhibits dezincification (a selective leaching corrosion) in waters that can attack brass fittings or other alloys. |

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 |

| Outside Diameter (OD) | Same for all types | ||
