CarTech 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 fine-grain, uniform quality magnetic core iron.

This alloy exhibits improved machining characteristics over CarTech 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 CarTech Silicon Core Iron "A" and are a function of the final heat treatment applied to the finish machined product.

Applications:
CarTech Silicon Core Iron "A-FM" has been used in producing solid cores which must be machined economically in volume.

This alloy is suggested for use in applications requiring a combination of moderately high electrical resistivity, high initial permeability, and low hysteresis loss in AC and DC circuits.
