Terfenol-D

Introduction:

A-one Alloy has rich experience of supplying various  Terfenol-D products.

Terfenol-D has the largest room temperature  magnetostriction of any known material. The name Terfenol originated from the  metallic elements, Terbium (TER) and Iron (FE); and the discovering  organization, Naval Ordnance Laboratory (NOL). Dysprosium (-D) was added as  an alloying addition later to reduce the magnetic fields required to induce  the magnetostrictive response. NOL, now known as the Naval Surface Warfare  Center – Carderock Division (NSWCCD) developed Terfenol-D for high power  sonar offering greater bandwidth and reliability over legacy technologies.  ETREMA holds key patents and licenses for many Terfenol-D applications,  including exclusive worldwide licenses to manufacture several types of  Terfenol-D materials. ETREMA is the world’s leading supplier of Terfenol-D  materials and products. Additionally, ETREMA provides assistance with the  design and manufacturing of Terfenol-D driven products.

Characters

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.

Application:

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.
