Advanced Glass-Coated Wire Technology

Glass-coated MicroWire production process

Glass-coated microwires are composite materials that consist of a metallic nucleus covered by glass shielding. They are prepared by drawing and rapid quenching of molten alloys and glass.

Engineered for Precision Sensing

They have unique properties in terms of the magnetization process and mechanical behavior, making them ideal for sensing various physical quantities in engineering applications.

Magnetic properties stem mainly from magnetoelastic interaction—the interaction of magnetic moments with a distribution of mechanical stresses induced during production.

Axial Stresses
Arise during the drawing and rapid quenching process, aligning magnetic moments along the wire's length.
Radial & Circular Stresses
Result from differing thermal expansion coefficients between the glass coating and the metallic core.
Shape Anisotropy
The wire's physical dimensions, such as diameter (3–70 μm) and length (1–4 cm), contribute to its magnetic properties.
