Tantalum Wire


Tantalum wire can take hydrogen, oxygen, and nitrogen away from the atmosphere and is the ideal product for vacuum applications in the lighting industry. It can be used in the manufacture of heating elements, vacuum tubes, and other high-temperature parts.

– As ion sputtering and spray materials
-High-temperature furnace parts
-Prosthetic devices for humans
-Tantalum electrolyte capacitors
-Vacuum electron cathode emission source

Edgetech Industries LLC specializes in providing high purity & uniform shaped tantalum wire with the highest possible density. We also supply tantalum tungsten alloy and tantalum niobium alloy wire.

Packaging of our Tantalum Wire

Our tantalum wire is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage to tantalum that might be caused during storage or transportation. The outer package is usually wooden crates.
