Tantalum has great conductivity of heat and electricity. Tantalum and tantalum alloy bars are widely used in:
Rods
-Ion sputtering and spray materials
-High-temperature furnace parts
-Prosthetic devices for humans
-Tantalum electrolyte capacitors
-Vacuum electron cathode emission source
We provide a Ta metal bar, and a tantalum cylinder (Ta cylinder) in a length of up to 2m. We also provide tantalum tungsten alloy and tantalum niobium alloy bars per request.

Packaging of our tantalum
ETI’s tantalum is tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage to Ta bars that might be caused during storage or transportation. The outer package is usually a wooden crate.
