Terbium Dysprosium Ferroalloy GMM has actuation and sensing functions. Stanford Materials Corporation (SMC) has rich experience in manufacturing and supplying high-quality Terbium Dysprosium Ferroalloy GMM.
GMM (Tb1-xDyxFe2-y) material has actuation and sensing functions. Actuation means that the size of the material changes under the action of a magnetic field, which can convert magnetic energy into mechanical kinetic energy. It is characterized by high precision, fast response speed, and large force. At the same time, GMM material has a piezomagnetic effect, that is, the magnetization state of the material changes under the action of external force, so it can be made into a sensor.
