Silicon Core Iron A

Silicon Core Iron A is melted in electric arc furnaces to exacting chemical specifications, and carefully controlled in rolling and annealing processes to produce a fine-grain, uniform quality magnetic core iron. Key benefits of this alloy include:

  • Medium electrical resistivity
  • High initial permeability
  • Low hysteresis loss in AC and DC circuits with moderate formability

Across the Board Improvement of Machinability

A modified grade of Silicon Core Iron A, known as Silicon Core Iron A-FM, contains a free-machining additive to improve its machinability, especially for screw machine operations. It has been used primarily for solid cores that must be machined economically in volume.
