MAGNESIL-O is an oriented silicon-iron alloy of exceptional magnetic qualities designed for applications involving frequencies of 400 Hertz and higher. It has pronounced directional magnetic properties in the direction of rolling. It is recommended for wound cores and stacked laminations which are sheared so that the magnetic flux is mainly in the direction of the strip length. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on forming and heat treating.
