Ultrasonic horns can be manufactured from different materials depending on the application, operating conditions and required performance. Titanium, aluminum and steel are commonly considered for ultrasonic tooling, with each material offering different characteristics in terms of strength, wear resistance, weight and machining requirements.
Horn material selection should take into account the application, amplitude, production volume, workpiece material and expected tooling life. For demanding applications, especially those involving abrasive or glass-filled materials, wear resistance can become an important consideration.
This guide compares common ultrasonic horn materials and explains how material selection can affect tooling performance and service life.
