CarTech 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.

A modified grade of CarTech Silicon Core Iron "A", known as CarTech 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 which must be machined economically in volume.

Applications:
CarTech Silicon Core Iron "A" has been used in applications requiring a combination of medium electrical resistivity, high initial permeability and low hysteresis loss in AC and DC circuits with moderate formability. It can be cold formed in the fully annealed condition.

Typical applications for this alloy have included solenoid switches, armatures, pole pieces, relays, etc.
