View Sample Alloy Digest Data Sheet (PDF)

Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.

Alfenol is an unoriented 12% to 16% aluminum-iron alloy which has high electrical resistivity and low eddy current losses. It is furnished in the 12% aluminum and in the 16% aluminum grades. The recommended uses are for relays, gyro mechanisms, servo-mechanisms and toroid tape cores.
