Tantalum is one of the most inert, unreactive metals known. Its primary use is in high power electronic capacitors and resistors. It is one of the best metals for this purpose as it confers a high capacitance in a small volume. This feature offers size and weight advantages in sophisticated hand-held electronic devices such as mobile phones and portable computers.

The chemical inertness of tantalum allows its use to medical and dental applications since the metal does not interact with body tissues. The industry uses this metal in:

  • artificial hip and knee joints
  • pins
  • screws
  • staples
  • other devices that hold bones together

Our customers use Tantalum also to produce superalloys that have:

  • high melting points,
  • excellent strength,
  • and good ductility.

Typical products that use Tantalum alloys are:

  1. laboratory equipment
  2. writing pen tips
  3. tools that operate at high speeds and temperatures.

Standard grades

Tantalum is sold as bars or rods.

Mineral origin

LKAB Minerals’ Tantalum originates from reliable sources in the U.S. and China.
