Magnetic Metals’ tape wound toroidal and tape wound cut cores are at the heart of today’s most advanced technologies. Electronic components containing our transformer cores achieve a near-perfect magnetic circuit unavailable with standard transformer laminations.

Magnetic Components

Pioneering Design and Fabrication

Founded in 1942, we have grown from supplying magnetic components to the U.S. military and NASA to providing tape wound transformer cores used in:

  • Power and navigation systems for the Aerospace and Defense industries;
  • Transformer assemblies and GFCI’s for electric vehicles and EV charging stations;
  • Power supplies and transformers for medical electronic devices and power electronics;
  • Communications equipment for the Telecom and Audio industries;
  • Voltage monitoring & measuring devices for industrial controls and electric utilities, and many other applications.
We engineer the highest quality magnetic cores and custom magnetic components.

We employ a team-based development process – utilizing our technical expertise in material selection, metallurgical processing and fabrication – to engineer the highest quality magnetic cores and custom magnetic components that meet our customers’ most stringent specifications and application requirements.

Applications and Products

Our tape wound toroidal cores (TWTC) utilize a winding configuration that provides a virtually complete magnetic circuit that is unachievable with lamination cores. Our cores are used in:

  • Voltage and current transformers,
  • Power supplies,
  • Motor controls,
  • GFCI’s,
  • HVAC systems,
  • Inductors, converters and inverters,
  • Input and output audio signals,
  • Computer modems,
  • Communications Controls,
  • Precision motor controls.

Our tape wound cut cores (TWCC) provide the critical dimensional and weight requirements not available in standard laminations for:

  • Transformers and assembly configurations,
  • Chokes,
  • Current transformers,
  • Pulse applications.

Advanced-Grade Materials

Magnetic Metals carries all types and thicknesses of soft magnetic materials with the most advanced magnetic properties and performance characteristics. They include:
