Products Description
Product Name |
C12000 Copper Plates |
|---|---|
| Material | C12000 Copper Plates is high-conductivity copper. It contains at least 99.99% copper and a tiny bit of oxygen and sulfur. This copper is strong, resists rusting, and can handle heat. It can be easily bent and shaped when cold and also formed when heated. This Copper Plate conducts electricity well, but less than pure copper. Its thermal conductivity is high and used for heat exchangers and thermal applications. It is easier to cut and shape. Improved weldability compared to standard copper due to the deoxidation process and less risk of cracking. It can be used for electrical components: bus bars, connectors, etc. Applications requiring good welding characteristics. |

FAQ
Q: What's the maximum continuous service temperature for C12000?
A: Typically up to about 150–200°C (302–392°F) for long-term service. Short-term exposure can go higher, but annealing and softening will occur above ~250°C (482°F).
Q: How should C12000 tubes be stored to prevent oxidation?
A: Store in a dry, covered area. For long-term storage or in humid climates, sealed plastic wrapping or nitrogen purging is recommended to prevent surface tarnishing.
Q: Can C12000 be bent easily?
A: Yes, especially in the annealed temper. For hard temper tubes, bending may require a mechanical bender to avoid kinking or cracking.
Q: What is the difference between TP1 (C12000) and TP2 (C12200) copper?
A: TP1 (C12000) and TP2 (C12200) are both phosphorus-deoxidized coppers, but they differ in residual phosphorus content: TP1 (C12000): Low residual phosphorus (0.004–0.012%). Designed for applications requiring high conductivity and good weldability, such as heat exchangers and electrical components. TP2 (C12200): Higher phosphorus content (0.015–0.040%). Offers improved weldability and brazability due to better deoxidation, but has slightly lower electrical conductivity (~80% IACS). Commonly used in plumbing, HVAC, and piping systems where welding/brazing is critical. Key takeaway: TP1 prioritizes conductivity, while TP2 prioritizes weldability and brazing performance.
