ADVANCING Soft Magnetic Ribbons MATERIALS. BUILDING A MORE EFFICIENT FUTURE.

We develop and manufacture ultra-thin nanocrystalline ribbons, magnetic cores, and soft magnetic components to support the evolving needs of electric vehicles and consumer electronics.

We bring together materials research and manufacturing—from alloy development to finished component production. Through continuous innovation in nanocrystalline materials and processes, we work with customers to turn application requirements into practical magnetic solutions.

Applications

As power systems advance toward higher switching frequencies and greater power density, magnetic materials play an increasingly important role in improving efficiency, managing energy loss, and enabling compact designs. FNM's soft magnetic ribbons provide the material foundation for a wide range of power electronics, EMI control, charging, and sensing applications.

Power & Energy Systems

From AC-DC and DC-DC converters to renewable energy and energy storage systems, efficient power conversion depends on effective magnetic design. Low-loss ribbon materials support magnetic core applications where energy efficiency, performance, and reliability are essential.

High-Frequency EMI Control

As SiC and GaN technologies enable faster switching, managing electromagnetic interference becomes increasingly challenging. Magnetic materials with suitable permeability and frequency characteristics support effective noise suppression in high-frequency power electronic systems.

Data Centers & AI Power

High-density server power supplies, 48V architectures, and advanced DC-DC converters demand greater efficiency in increasingly compact spaces. Appropriate magnetic core materials help manage energy losses and thermal performance while supporting higher power density.

EV & Charging

On-board chargers, charging infrastructure, and vehicle power conversion systems require efficient and reliable magnetic components. Material selection plays an important role in reducing magnetic losses, supporting compact designs, and maintaining performance under demanding operating conditions.

Wireless Charging & Shielding

Wireless power transfer relies on controlled magnetic flux and effective shielding to achieve efficient energy transmission. Thin magnetic ribbon materials offer potential options for flux guidance and shielding structures in compatible consumer electronics and automotive charging designs.

Current Sensing & Protection

Accurate current measurement and protection depend on magnetic materials with suitable permeability, sensitivity, and stability. Nanocrystalline materials are widely used in sensing cores for residual-current devices (RCDs), energy metering, current transformers, and current-monitoring systems.
