Stable and Reliable Performance
Precision Sensing and Control: Used in the manufacture of high-precision torque sensors, stress detection elements, and micro-displacement controllers. Their magnetostrictive effect enables non-contact, precise measurement and control.
Ultrasonic and Vibration Equipment: As a core driving material, applied in sonar, ultrasonic cleaning, medical ultrasound imaging, and vibration energy harvesting devices, achieving efficient electromechanical energy conversion.
Active Vibration Damping and Noise Reduction: Used in intelligent structures of precision machine tools and aerospace vehicles, effectively suppressing system vibration and noise by generating real-time reverse vibration.
Advanced Intelligent Devices: One of the key materials for core actuation units in the development of novel microelectromechanical systems, magnetic memories, and adaptive optics devices.
Q1: What is the “magnetostriction coefficient”?
A1: It measures the degree to which a material changes length in a magnetic field. Our FeGa alloy particles have a very high saturation magnetostriction coefficient, meaning that even a weak change in magnetic field can produce significant deformation or force output.
Q2: Does temperature significantly affect material properties?
A2: It has some effect. Magnetostrictive properties change with temperature. We can provide alloys with optimized compositions to balance performance and temperature stability, based on your application’s temperature range.
Q3: What shapes and sizes of particles are available?
A3: We mainly provide irregularly shaped particles, but can also provide customized products of specific sizes based on subsequent melting or processing requirements.
Q4: How to prevent oxidation during use?
A4: Gallium-iron alloy granules are relatively stable in air, but it is recommended to store them in a dry environment. Melting or high-temperature processing should be carried out in an inert gas or vacuum environment to prevent excessive surface oxidation.
