There is no difference. Silicon, the old name of the chemical element "silicon". Silicon steel sheets are silicon steel sheets.
Silicon steel sheets for electrical purposes are commonly known as silicon steel sheets or silicon steel sheets. As the name suggests, it is electrical silicon steel with a silicon content of up to 0.8%-4.8%, which is made by hot and cold rolling.
Generally, the thickness is less than 1mm, so it is called thin plate. Silicon steel sheets broadly speaking belong to the plate category and are an independent branch due to their special uses. Silicon steel sheets for electrical purposes have excellent electromagnetic properties and are indispensable and important magnetic materials in the power, telecommunications and instrument industries.
