Magnetostrictive Rare Earth Materials GMM TbDyFe Alloy Round Bar 10mm

Magnetostrictive Rare Earth Materials GMM TbDyFe Alloy Round Bar 10mm

Introduction

Giant Magnetostrictive Materials have a very wide range of applications, such as naval, military (sonar), mechanical industry, electronics, petroleum, textile, aerospace, instrumentation, agriculture and civil use. These applications greatly improved the related industries’ technology, such as high-power GMM transducers for well treatment, which can reduce oil viscosity, improve the flow characteristics, and greatly improve oil production. In the new century of science and technology, the importance of GMM will be more and more prominent, and the application will expand rapidly.

Applicaiton

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.

We can supply Giant magnetostrictive Material in forms of Rod, bar, and other customized shapes are available per request.

General Rod stock diameters: 10mm and 28mm, other specifications can be customized.

In addition, slot opening, cascades and other processing services also can be provided.
