Silicon Iron Alloys
Silicon Iron Alloys Silicon Iron alloys are generally used in applications requiring higher electrical resistivity, higher permeability, lower coercive force and residual magnetism than provided by either carbon steels or soft magnetic stainless steels such as the Magivai® series.
Valbruna grades of Silicon Iron alloys are classified according to the Silicon content in the chemical composition according to the standard classification of ASTM A 867.
Each single grade has got its enhanced machinability option where required.
Silicon Iron alloys are normally supplied in the annealed condition since the best magnetic properties can be reached through a soft magnetic annealing carried out after part machining.
Silicon Iron alloys rust easily under ordinary atmospheric conditions and therefore a protective coating should be applied to the heat treated parts if exposed during their life cycle.
Due to their high magnetic properties, Silicon Iron alloys are mainly used in the manufacture of relays, solenoids and injectors parts.
