Company Profile (ETREMA Products, Inc.)

ETREMA Products, Inc. logo
ETREMA Products, Inc., a world leader in magnetostrictive technology development, was founded in 1987 to produce the giant magnetostrictive material (GMM), Terfenol-D. Since that time, Etrema has expanded its capabilities to include the design and manufacture of devices based on magnetostrictive technologies. Some of these devices include Active Machining Systems (AMS) Technology which enables the production of high tolerance, non-round components; devices that exploit the sono-chemistry phenomenon - cavitation, next generation sonar, and vibrational energy harvesting. ETREMA is also a leading industrial partner to universities and government labs in the research and development of new magnetostrictive materials, such as Galfenol. Galfenol offers a unique combination of properties not exhibited in most active materials; a large magnetostrictive response in a mechanically robust alloy.
