Tantalum Wire (Ta 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. Tantalum wire is corrosion resistant and has good thermal conductivity. Tantalum wire can be used in manufacture of heating elements, vacuum tubes and other high temperature parts.

Edgetech Industries LLC specializes in providing high purity & uniform shaped tantalum wire with the highest possible density, tantalum wire can be used in semiconductor, chemical vapor deposition (CVD) and PVD, etc. We also supply tantalum tungsten alloy wire and tantalum niobium alloy wire.

Tantalum has great conductive of heat and electricity. Tantalum wire is 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 Wire

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