Our pure tantalum rods are cold rolled and voided in a proprietary process that creates metallurgical properties ideal for applications such as spraying gun barrels, processing into fixtures, x-ray or radiation shield, medical markers for surgeons, vacuum furnace heating elements, chlorinator springs, components for light bulbs, or processed parts for chemical processing equipment.

Applications

- Ion atomization and atomization materials
- High temperature oven parts
- Prosthetic devices for humans
- Tantalum electrolyte capacitors
- Vacuum electronic cathode emission source
