Shows an overview of which surfaces or materials can be soldered with which flux or process.
The matrix is shown in the following table:
| Material | Flux RMA | Flux RA | Flux WS | Flux WS-H | Flux NC | HCOOH | H2 | Plasma |
| Aluminum | x | x | x | x | x | x | x | x |
| Brass | ~ | ok | ~ | ok | ~ | ~ | ~ | ~ |
| Bronze | ~ | ok | ~ | ok | ~ | ~ | ~ | ~ |
| Chromium | x | x | x | x | x | x | x | x |
| Copper | ok | ok | ok | x | ok | ok | ok | ok |
| Steel | x | ok | x | ok | x | x | x | x |
