Press Release - EEC awarded Patent For Ultra-High Temperature magnets

Electron Energy Corporation Awarded Patent For High-Temperature Magnets

LANDISVILLE, PA (October 18, 2002) — Electron Energy Corporation, a long-standing innovator in the field of rare-earth magnets, has been awarded U.S. Patent No. 6,451,132 B1 on their new series of rare-earth cobalt magnets for high temperature applications. These high temperature magnets, properly coated, are suitable for long-term service at temperatures as high as 550

Since 1995, the U.S. Air Force and other branches within the U.S. Department of Defense have described requirements for magnets capable of operating at temperatures greater than 400°C. In response to those needs, Electron Energy Corporation (EEC) has developed this new class of magnets.

EEC’s objective during the development of these magnets was to maintain a substantially linear extrinsic demagnetization curve at higher temperatures while maintaining the maximum possible energy product. Accordingly, a new symbol (TM) was introduced, which is defined as the maximum temperature at which the extrinsic demagnetization curve of a magnet is a straight line. A straight-line extrinsic demagnetization curve is of value to designers of minimum volume and minimum weight devices. The straight-line curve is even more important for dynamic or highly loaded applications where high demagnetization forces are encountered.
