Amorphous Cores

Our amorphous-alloy cores provide a wider range of high frequency properties and lower core losses than other soft magnetic materials.

Amorphous Alloys are metallic glass materials without a crystalline structure. Amorphous-Alloy Cores provide better electrical conductivity, higher permeability and magnetic density, and efficient operation over a wider temperature range than cores made from conventional materials. Smaller, lighter, and more energy-efficient designs are possible for transformers, inductors, invertors, motors, and any device requiring high frequency, low loss performance.

Advantages of using amorphous cores:

  • High permeability
  • High magnetic density
  • Reduced distribution and core losses
  • Wide range of frequency properties
  • Low coercivity forces
  • Low no-load loss
  • Low temperature rise
  • Affordably priced
  • Excellent resistance to corrosion
  • High harmonic wave tolerances
