The cored wire is made of strip-shaped steel strip wrapped with alloy powder. According to the different alloy powders, it can be divided into calcium silicon cored wire, silicon manganese calcium wire, calcium silicon barium wire, barium aluminum wire, aluminum calcium wire, calcium iron wire, pure calcium wire, etc. The winding looks like a coil.
