High Performance Materials

Sheet [Ta] [Nb]

For more Information

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
