Sheet [Ta] [Nb]
Ta/Nb sheets from ULVAC have a fine and uniform grain size. This makes it possible to produce high-yield foils with light surface roughening after pressing and uniform intensity and characteristics.
Available process size
10µm to 35mm, Width Max 1100mm
Plate supply size
(Unit:mm)
| Plate thickness | Length | Width |
|---|---|---|
| 0.6 | 4,500 | 1,200 |
| 1.0 | 3,500 | |
| 1.6 | 2,200 |
* That plates can be made longer by welding. (Past production record: 30 mm)
Use
- Diaphragms for differential pressure transmitters
- Film capacitors
- Boards for deposition
- Foils for getters
- Heat treatment reflectors
- Heaters
Problems with structure in pressing
Structures of tantalum foils with different grain sizes after pressing
Comparison of tantalum foil structures from different manufacturers
