Silicon Steel

Silicon steel is a soft magnetic alloy produced by adding silicon to iron (typically at a concentration of 0.5% to 4.5%). It is an indispensable functional material in the power, electronics, and defense industries, and is primarily used to manufacture the cores of various motors, generators, and transformers.
