Terbium dysprosium iron (Terfenol-D), Sputtering Target, 99.95%, 2 inch dia x 0.25 inch th.

Terfenol-D is utilized as a sputtering target material to deposit magnetostrictive thin films for use in micro-electromechanical systems (MEMS) and precision sensors.

As a giant magnetostrictive alloy composed of terbium and dysprosium, it is used in high-power transducers, actuators, and sonar systems due to its ability to change shape under magnetic fields.

The precise alloying of terbium, dysprosium, and iron creates a material with the highest known magnetostriction, essential for specialized engineering applications requiring high force and displacement.
