Tantalum has great conductive of heat and electricity. Tantalum rods & bars are widely used in:

  • Ion sputtering and spray materials
  • High temperature furnace parts
  • Prosthetic devices for humans
  • Tantalum electrolyte capacitors
  • Vacuum electron cathode emission source

Packaging of Ta rods & bars

ETI’s Ta rod and bar is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage on product which might be caused during storage or transportation. Outer package for tantalum is usually wooden crate.
