Grain-oriented electrical steel - alloy of Fe with up with 6.5% Si, optimised for its magnetic properties, manufactured in laminations or thin sheets (typically less than 0.5 mm) and with crystals of each grain aligned accordingly with respect to the rolling direction. ¹⁾²⁾³⁾

Chemical composition of grain-oriented electrical steels:⁴⁾ typically electrical steels contain around 3% of silicon (but it can vary between 0.2–3.4%), sometimes with addition of aluminium; the balance is iron. Special steel can contain up to 6.5% of Si.
