CarTech Silicon Core Iron "B-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 "B". Improvements in machinability of up to 40% have been realized on automatic screw machines.

In addition, CarTech Silicon Core Iron "B-FM" displays lower residual magnetism, higher electrical resistivity, and is more magnetically soft when heat treated under identical conditions than CarTech Silicon Core Iron "B".

The magnetic characteristics and cold working/cold forming properties of CarTech Silicon Core Iron "B-FM" are in the same range as CarTech Silicon Core Iron "B".

Applications:
CarTech Silicon Core Iron "B-FM" has been used in solenoid switches, armatures, pole pieces, relays, etc.

This alloy should be considered for use in applications requiring a magnetic core component superior to mild steel, magnetic iron (99.2% Fe minimum) and a 1% silicon core iron.
