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 our 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 Ta rods & Ta bars which might be caused during storage or transportation. Outer package for tantalum is usually wooden crate.
