A Truly Superior Magnetic Core Component
This alloy exhibits improved machining characteristics over Silicon Core Iron B. Improvements in machinability of up to 40% have been realized on automatic screw machines. In addition, Silicon Core Iron B-FM displays lower residual magnetism, higher electrical resistivity, and is more magnetically soft when heat treated under identical conditions than Silicon Core Iron B. The magnetic characteristics and cold working/cold forming properties of Silicon Core Iron B-FM are in the same range as Silicon Core Iron B.
