Pure Tantalum Rod

Raytec metal offers our customers an impressive selection of tantalum rod and bar sizes which are all engineered for a range of applications. Our products are cold rolled and annealed in a proprietary process which creates metallurgical properties ideal for such applications as sputtering gun barrels, machining into fasteners, x-ray or radiation shielding, medical markers for surgeons, vacuum furnace heating elements, chlorinator springs, components for light bulbs, or machined parts for chemical processing equipment.
