Sinto’s magnetic metal powders

Magnetic metal powder is primarily used as a core material in electronic components found in communications devices (including smartphones and those installed in automobiles) and controllers.
Designed using our surface treatment blasting media (steel shot) technologies developed over decades, our magnetic powders are crafted to achieve minute particle sizes and high reliability. As a result, we are able to mass-produce magnetic metal powders with an average particle diameter of just two microns.

Only possible with micron-level magnetic powders

Lamination

The use of ultrafine powder helps create smaller, lower-profile electronic components

High-density filling

Filling in the spaces between granules creates a high-density fill with better magnetic performance for smaller electronic components.

Thinner sheets

Finer granules keep surface unevenness to a minimum for thinner sheets.

Higher-frequency applications

Sinto’s unique amorphous structure delivers low-loss, low-anistropic, low-resistance performance. The addition of an insulated coating can reduce loss even further.

Applications
