What Is Annealed C12000 Copper?
C12000 copper plate itself has high strength, high electrical conductivity, high thermal conductivity, as well as excellent corrosion resistance and good machinability. After annealing treatment, the properties of C12000 copper sheet may be further enhanced, such as improving ductility and toughness, and reducing hardness to make it easier to machine and form. At the same time, the annealing treatment may also optimize its electrical conductivity, ensuring the quality and efficiency of signal transmission.
Why Choose Annealed C12000 Over Other Copper Grades?
| Grade | Type | Key Feature | Best For |
|---|---|---|---|
| C12000 (Annealed) | Phosphorus-Deoxidized | Soft, ductile, weldable | Forming, bending, flaring |
| C11000 (ETP) | Electrolytic Tough Pitch | High conductivity | Busbars, electrical parts |
| C10100 (OFE) | Oxygen-Free Electronic | Ultra-high purity | Semiconductors, vacuum |
| C12200 (DHP) | Phosphorus-Deoxidized | Similar to C12000 | Plumbing, HVAC |
Key advantages of annealed C12000:
Superior formability – Easily bent, flared, or shaped
Excellent weldability – No hydrogen embrittlement risk
Good conductivity – ~85–98% IACS
Cost-effective – More affordable than OFE grades

C12000 annealed copper sheet has a wide range of applications in electrical, automotive, aerospace, and electronics fields. Its excellent electrical and thermal conductivity makes it particularly suitable for making electrical products such as cables, wires, and radiators, while its high strength and corrosion resistance make it suitable for automotive and aerospace components.
FAQ
Q: What does "annealed" mean?
A: Annealing is a heat treatment process that softens the copper, making it more ductile and easier to form. Annealed C12000 is supplied in the softest possible condition.
Q: Can annealed C12000 be welded?
A: Yes! C12000 is phosphorus-deoxidized copper, specifically designed to resist hydrogen embrittlement during welding and brazing.
Q: What is the difference between C12000 and C11000?
A: C11000 (ETP copper) contains oxygen and can suffer from hydrogen embrittlement if welded. C12000 is deoxidized with phosphorus, making it weldable but with slightly lower conductivity.
Q: Does annealed copper harden over time?
A: At room temperature, no. However, if you bend or work the copper (cold working), it will work-harden. It can be re-annealed if further forming is needed.
