Tantalum [Ta], Niobium [Nb] Sheet

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


Plate Thickness      Length        Width     
0.6 4,500 1,200
1.0 3,500 1,200
1.6 2,200 1,200

 *That plates can be made longer by welding. (Past production record: 30 mm)
