ETREMA Products Terfenol-D Magnetostrictive Smart Material (Tb_0.3Dy_0.7Fe_1.92) (discontinued **)
Categories:	Metal; Electronic/Magnetic Alloy
Material Notes:	Terfenol-D is the commercial name for Tb_0.3Dy_0.7Fe_1.92; a composition of material that exhibits giant magnetostriction. Magnetostriction is the phenomenon in which an applied magnetic field causes an anisotropic change in length in the material (Joule effect) or a change in the stress state of the material changes its magnetic properties (Villari effect). Magnetostrictive alloys have a wide range of applications in the areas of ultrasonics, sensors, audio, and transducers such as: Actuators Seismic tools Non-round machining High-powered ultrasonics Sonar Fuel injection Vibration control Information provided by ETREMA Products.
