Weldability and physical characteristic of each welding material and guideline for the electrode material selection are introduced.
The list below shows rough standards to choose materials for an electrode, though it may be changed according to its surface treatment or dimensions.
| Electrode Number | Alloy Components | Electric Conductivity (IACS%) |
Applicable Metal |
|---|---|---|---|
| 02 (equivalent to RWMA-2) | Cu-Cr-Zr | around 80% | iron, nickel, chrome and their alloys |
| 03 (equivalent to RWMA-3) | Cu-Ni-Be | around 50% | phosphor bronze, brass |
| 00 | pure Mo | around 31% | tinned copper wire, solder plating copper wire |
| 11 (equivalent to RWMA-11) | Cu (30%) -W (70%) | around 46% | noble metal |
| 13 (equivalent to RWMA-13) | pure W | around 32% | copper |
| 20 | Cu-Al2O3 | around 80% | Battery Tab |
