Product Description

Terfenol-D Magnetostrictive Material Round Rod Diameter 10-80mm


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


As a material with multiple functions, it can be used in many different fields. Till now, more than 1000 kinds of different device have been developed, covering the fields of machine tool industry, electronic industry, oil industry, textile industry, aircraft and aerospace, agriculture as well as civil use. All these development do active advances in the regarding industry areas. For example, the use of the high power GMM transducer to treat the oil well reduces the viscosity of oil therefore increases the output of the oil greatly.


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.
