Terbium Dysprosium Iron (Terfenol-D) Sputtering Target, Round Terbium Dysprosium Iron Target, Purity 99.9%

Terbium Dysprosium Iron (Terfenol-D) Sputtering Target (Tb0.3/Dy0.7/Fe1.9)

Terfenol-D is an alloy comprised of Terbium, Dysprosium and Iron. Terfenol-D has the largest room temperature magnetostriction of any known material. 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 (380℃), which enables magnetostrictive performance greater than 1000 ppm from room temperature to 200¡ãC. Adjustments in alloy composition can extend this range down to cryogenic temperature.

Material Notes

Terbium dysprosium iron (Terfenol-D) Sputtering Targets, Purity is 99.9%; Circular: Diameter <= 14inch, Thickness >= 1mm; Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm. In addition, TdVib can tailor the Terfenol-D composition to allow for a wider operating temperature range. By adjusting the Tb:Dy ratio large magnetostriction values can be achieved at temperatures as low as -200¡ãC and as high as 200¡.
