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 is corrosion resistant and has good thermal conductivity. It can be used in the 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, it can be used in semiconductors, chemical vapor deposition (CVD) and PVD, etc. We also supply tantalum tungsten and tantalum niobium alloy wires.

Tantalum has great conductive of heat and electricity. Ta 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
Our tantalum is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage on items which might be caused during storage or transportation. Outer package is usually wooden crate.
