 Ultrasonic Actuator Specs
Terfenol-D provides ultrasonic systems with unprecedented power, and continuous operation at
any power level. The National Institute of Science and Technology (NIST) has recognized
Terfenol-D as an enabling technology, which will be a key player in the future ultrasonic
industry, and take it into entirely new fields of application. Many ultrasonic processes
discovered in the laboratory had never been commercialized until Terfenol-D driven equipment
was introduced.

Specifications
The following table identifies the performance of the Terfenol-D ultrasonic
magnetostrictive actuators. Each actuator is available with a Metric or English threaded
connection. Metric connections are specified by -MS1, and English by -ES1.

ETREMA power ultrasonic systems are creating a renaissance in the fields of sonochemistry,
ultrasonic welding, oil treatment, bacteria elimination, industrial process improvement,
food processing, waste material conversion and ultrasonic machining. ETREMA provides
ready-to-use ultrasonic systems and components, and develops custom equipment now
used in many industries. ETREMA engineering has the tools and experience to develop
systems that efficiently deliver the unprecedented power of Terfenol-D.

Chemical processes such as polymerization can be commercialized using Terfenol-D
Ultrasonics. Several processes for ultrasonic destruction of environmentally damaging
materials are in final stages of development. ETREMA is producing several types of
Terfenol-D driven hand tools. Since Terfenol-D is a low voltage, current driven
magnetostrictive material, hand tools can be made safer. The high energy density of
Terfenol-D also allows hand tools to be made smaller. Commercial processes are being
developed to weld materials that could not be previously joined by ultrasonic equipment.
