Silicon Core Iron A-FM

Silicon Core Iron A-FM is melted in electric arc furnaces to exacting chemical specifications and carefully controlled through all manufacturing processes to produce a finegrain, 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

Achieving Lower Hysteresis Loss

This alloy exhibits improved machining characteristics over Silicon Core Iron A. Improvements in machinability up to 40% can be realized on automatic screw machines. The magnetic characteristics are of the same order exhibited by Silicon Core Iron A and are a function of the final heat treatment applied to the finish machined product.
