Terbium dysprosium iron (Terfenol-D), Sputtering Target, 99.9%, 3 inch dia x 0.125 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 an alloy of terbium and dysprosium, it leverages the unique magnetic properties of rare earth elements to achieve the highest known magnetostriction of any alloy.

The precise alloying of terbium, dysprosium, and iron creates a giant magnetostrictive material used in high-power transducers and sonic actuators.
