Titanium Materials

Iron-Based Amorphous Single-layer Strip

High Grade Non-oriented Electrical Steel

It is a ferrosilicon alloy containing 0.8%-4.8% silicon. After hot and cold rolling, it becomes a silicon steel sheet with a thickness of less than 1mm. Adding silicon can increase the resistivity and maximum permeability of iron, reduce the coercive force, core loss (iron loss) and magnetic aging, and is mainly used as the iron core of various motors, generators and transformers.
