Transformer manufacture. Building cores for power transformers is highly skilled work. A new electric steel called hipersil is used in these cores, a steel which makes it possible to build smaller cores, and therefore use less copper and steel, both virtually needed elsewhere in the war program. In addition, this hipersil carries one third more magnetic flux than ordinary steel. Westinghouse, Sharon, Pennsylvania
