Tantalum has great conductive of heat and electricity. Tantalum rods & tantalum 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 Tantalum Rod & Tantalum Bar
ETI’s tantalum rod and tantalum 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 rod and tantalum bar is usually wooden crate.
