Ready-made solutions for electromagnetic shielding

Amid widespread digitalization and growing electrical equipment capacity, ensuring electromagnetic compatibility becomes acute. People’s safety and uninterrupted operation of sensitive apparatus require modern, effective, reliable solutions. Exactly such a solution is our strip from a precision soft magnetic alloy developed for highly effective electromagnetic shielding.

An invisible threat requires visible protection

Power transformers, reactors, and high-power converters are sources of intense industrial-frequency magnetic fields. These fields not only create interference for electronic equipment but, according to recent studies, may negatively affect human health under prolonged exposure. Placing workplaces or residential zones in immediate proximity to such facilities becomes a serious engineering task.

Why a soft magnetic alloy?

Unlike shielding from an electric field, suppressing the magnetic component requires materials with special properties: high magnetic permeability in weak fields and low eddy current losses. Ordinary materials such as aluminum or copper cannot effectively shield a low-frequency magnetic field. Only specialized soft magnetic alloys handle this task.

Our strip is produced from a nickel- and iron-based alloy by a unique technology that ensures:

• Exceptionally high initial and maximum magnetic permeability. This effectively “closes” the stray-field magnetic flux inside the shield, significantly reducing its impact on the external environment.
• Low specific hysteresis and eddy current losses. This guarantees the shield will not overheat in operation, retaining its properties for decades.
• High saturation induction. This is critically important for shielding high-power equipment without loss of shield efficiency.

Our key advantage is not merely a material — it is a precision product.

We understand that parameter stability of every material batch is the key to your project’s success. Therefore we pay special attention to quality control at all production stages: from melting and chemical composition to final heat treatment.

Applications

• Shielding enclosures and chambers for power transformers at substations, including those built into residential and office buildings.
• Protection of medical facilities (MRI rooms, diagnostic centers) from external and internal interference.
• Ensuring electromagnetic compatibility at energy facilities, machine-building and research enterprises.
• Shielding residential and non-residential premises from high-voltage power lines, overhead lines, and the like.
