3% (Grain-Oriented) Silicon Steel is a soft magnetic material that is best used in electrical power transformers and inductors. It has a silicon content up to 3.2 mass %, which increases the electrical resistivity and reduces eddy current losses. The magnetic properties can be enhanced during a cold rolling stage (along the length) to produce textured sheets, known as grain-oriented electrical steel. Due to its
preferred crystallographic orientation, it is used primarily for non-rotating applications, i.e. transformers and inductors. Typical operating frequency of 3% Silicon Steel is 50-60 Hz (hertz). A variety of forms can be manufactured, including lamination, toroidal and C-cores, as well as glued block cores of various shapes by cutting or pressing.
