Product Description


Rare Earth Giant Magnetostrictive Material Terfenol-D Round Rod


Xunshi is one of the leading supplier in magnetostrictive materials,such as Rare Earth Giant Magnetostrictive material Terfenol-D and GMM, TD-plus,Galfenol,magnetic control shape memory alloy (MSMA) Ni-Mn-Ga,magnetostrictive waveguide wire,iron cobalt vanadium alloy,iron-nickel alloy,pure nickel,iron aluminum alloy,etc.


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 (380°C), which enables magnetostrictive performance greater than 1000 ppm from room temperature to 200°C. Adjustments in alloy composition can extend this range down to cryogenic temperatures.



Magnetostrictive coefficient: It is 50 times larger than Ni and 5 ~ 25 times larger than piezoelectric ceramics (PZT)

Large strain thrust: Terbium dysprosium ferroalloy rods of 10mm in diameter produce a thrust of about 200 kg

Electromechanical coupling coefficient :70%, Nickel-based alloy: 16%, PZT Material 40~60%

Fast response time: About a million of a second, faster than people think

Elastic modulus: can vary with the magnetic field, can be regulated

Good stability and high reliability


The froms of Terfenol-D we supply are mainly round rods in diameter 10-80mm,and the length can be made according to customer requirements. We can cut and process the materials, provide square bars, squares and other products of different shapes and sizes, to meet the different needs of different customers. In addition, we can also provide customers with slot, stacking and other processing.


For customized shapes,please feel free to contact us.
