Blocks are manufactured with both iron based amorphous and nanocrystalline alloy. These blocks offer a unique combination of high saturation induction, high permeability and low losses.

These Blocks can be arranged in different layouts.


  • Output Filter or Inductor cores in High Frequency and High Power (generally > 50KW)
  • Solar and wind inverter


  • High Saturation Flux Density (Reducing volume and weight of the core)
  • Low core loss – Lower temperature rising, higher efficiency of the transformer
  • High Permeability
  • Excellent temperature stability – Keep stable working at -50ᵒC - 130ᵒC for long time
