Description
Tantalum has great conductive of heat and electricity. Tantalum rod 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
Edgetech provides tantalum rod, cylinder (Ta cylinder) in the length of up to 2m and in diameter of up to 120 mm. We also provide tantalum tungsten alloy and tantalum niobium alloy rod per request.
