Silicon steel (electrical steel) refers to a very low carbon ferrosilicon alloy with a silicon content of 0.5% to 6.5%. Due to differing structures and applications, they categorize silicon steel into non-oriented and oriented types. Various motors, generators, compressors, and transformers primarily utilize silicon steel as their core material. It is an indispensable raw material product in the electric power, home appliances and other industries. B50A470 cold-rolled electrical steel is widely used in the manufacture of motor cores. In this article we will focus on the properties of B50A470 non-oriented silicon steel.
