Terfenol-d Rare Earth Giant Magnetostrictive Alloy

We are engaged in manufacturing and exporting excellent quality Terfenol-D Rare Earth Giant Magnetostrictive Alloy in Suzhou, Jiangsu Sheng, China.

Characters
Terfenol-D is an alloy comprised of Terbium, Dysprosium and Iron. Terfenol-D is a solid-state material capable of converting energy from one form to another. In the case of electrical-to-mechanical conversion, the magnetostriction of the Terfenol-D generates strains 100 times greater than traditional magnetostrictives, and 2-5 times greater than traditional piezoceramics. The material has a high Curie temperature (380A C), which enables magnetostrictive performance greater than 1000 ppm from room temperature to 200A C. Adjustments in alloy composition can extend this range down to cryogenic temperatures.
