High-temperature effects on magnetic core materials

A STUDY of the effects of high temperature on the properties of magnetic core materials was made to facilitate the development of military components for operation under extreme environmental conditions. The following materials were studied: Transformer A; Audio Transformer A, L and Z Silectron; Orthonol; AEM 4750; 4–79 Mo Permalloy; 11.7 Alfenol; 15.5 Alfenol; 3 Mo Thermenol; Supermendur; and 7–70 Perminvar.
