Tantalic
the ingots
They are let out by the diameter of 60-130 mm and they are supplied by long to 750 mm.
with the machined surface or with the surface, fused
by electron beam. A mass fraction of tantalum is not less than 99,8%.
A mass fraction of admixtures/impurities must not exceed those indicated in the table.

Bars are tantalic
Bars are made by diameter from echo to 90 mm, the dependence
from the diameter the bars are made by length from 100 to 2000 mm. with that following
by the turning of surface or without it.
Impurity content is identical to admixtures/impurities in the tantalic ingot.

Wire is tantalic
Wire is made by diameter from 0,05 to echo mm.
The wire with a diameter of more than 1 mm is supplied in the technological lubricant. In
dependence on the diameter the actual length of wire from 150 to 2000 m.
The impurity content in the capacitor wire (0,15-1,0 mm) is identical to
the admixtures/impurities in the tantalic ingot.

Sheets are tantalic
Sheets are let out by the thickness of 0,05-10 mm, by width 50-150
mm, with the length not are less than 300 mm.
Impurity content is identical to admixtures/impurities in the tantalic ingot.
Price for the sheets with NDS:
