Product Description

Crispy improved large Magnetostrictive Material Terbium dysprosium ferroalloy Terfenol-D


Super magnetostrictive material (GMM) is an intelligent material that integrates ring energy, actuation, sensing and other functions, It can be used to make audio transducers, water acoustic transducers, ultrasonic transducers, vibrators, precise displacement actuators, and sensors, GMM can be used to make new type audio, ultra-precision machine tool feed system, robot arm mechanism, precision valves, precision pumps, high-power aquatic sonar transmitters, and active shock and noise reduction system, etc Its advantages are high power, high displacement, high efficiency, wide frequency band, high precision, fast response speed and high reliability.

Traditional terbium dysprosium ferroalloy Terfenol-D limits its scope of application due to its brittle material and poor mechanical properties. After years of experimental exploration, we successfully solve the brittle problem of traditional GMM, and improve the processing performance while ensuring its magnetoscalability performance, so that we can process the material through traditional processing means.



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

Product manufacturing process:

Raw material-- vacuum melting-- vacuum pouring -- vacuum directional solidification --heat --treatment --cutting --detection -- packaging ---out stock.


The materials 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 , we also can provide square bars, squares and other products of different shapes and sizes to meet the different needs of different customers. In addition, we could provide customers with slot, stacking and other processing.
