Abstract
A ultrasonic tool horn for use in ultrasonic machining, welding, etc. has a horn main body made of a heat-treatable aluminum alloy. The aluminum alloy is heat treated so as to be as hard as 100 or more on the Vickers hardness scale. In one embodiment, a thin intermediate layer of a non-heat-treatable aluminum alloy is provided between the horn main body and a ceramic tool attached to a slender end portion of the horn main body.
