A major advance in magnetic materials

Abstract

Within the space of one week last year, the two leading producers of electrical equipment, General Electric Co. and Westinghouse Electric Corp., both announced the development of a cube-oriented silicon-iron transformer sheet.

Below, Journal of Metals presents two papers, one from Westinghouse, on the nature and uses of the new material, and one from General Electric, describing its magnetic properties.

Although not mentioned in the papers, the General Electric product is called “Four-Square,” while Westinghouse has chosen “Cubex” as the trade name for its cube-oriented sheet.
