Materials
A complete selection of all soft magnetic materials from specialised market leaders.
Choose from a complete selection of soft magnetic cores from leading manufacturers. We offer ferrite, powder cores and nanocrystalline solutions tailored to your requirements.
Powder cores from Micrometals
Powder cores are cores with an air gap distributed across the entire magnetic path, resulting in high pre-magnetisability and soft saturation behaviour.
Our range includes:
- Iron powder cores
- Alloy powder cores (Sendust, MPP, etc.)
Ferrites from DMEGC
Ferrite cores are technical ceramics with optimised soft magnetic properties. Here, pre-sintered granulate is pressed into the desired shape and sintered in a process lasting several hours.
Our range includes:
- MnZn power ferrites
- Broadband and EMI ferrites
- Inductive proximity switches
Nanocrystalline cores from DMEGC
Nanocrystalline cores are wound from thin strips with a thickness of approx. 16 μm. This enables high permeability of up to 800,000 and high saturation with excellent temperature stability.
Our range includes:
- Nanocrystalline cores
- Amorphous cores
Core shapes
From toroidal cores to E-cores: common designs for different areas of application.
Our cores are available in various geometries to meet mechanical, electrical and thermal requirements. Whether compact design, optimised windability or low stray field emission, the choice of core shape has a significant influence on the performance of your application.

Renewable energies
Reliable soft magnetic cores with high power density are required for the conversion and feed-in of renewable energy. Our products offer stable inductance with changing load profiles, low losses at high frequencies and resistance to temperature fluctuations. Ideal for solar inverters, wind turbines and DC link filters in battery storage systems.
Medical technology
In medical applications, electromagnetic compatibility is just as crucial as precision signal processing. Our ferrite and iron powder cores help to comply with critical EMC limits and ensure stable magnetic circuits in diagnostic, imaging and therapeutic devices. Their compact design and high material purity make them ideal for use in sensitive environments.

Automation & control technology
In industrial automation, magnetic components must function reliably under changing loads. Our products offer low losses, constant permeability and thermal robustness in applications such as servo drives, robotics and decentralised control units. This ensures precise signal transmission and smooth process flows.

Aviation
Space is limited and reliability is crucial in aircraft controls and on-board electronics. Our nanocrystalline and ferrite cores combine high saturation stability with low weight and excellent EMC behaviour. They are particularly suitable for demanding applications in communication and safety systems that must function continuously.
