The solid-state nature of the ultrasonic bonding process used in UAM permits joining of dissimilar metals without the formation of brittle inter-metallics as seen in fusion processes. A wide range of material combinations have been successfully bonded using ultrasonics. Al/Cu, Al/Fe and Al/Ti are routinely joined. Fabrisonic has also worked with exotic combinations such as Ta/Fe, Ag/Au and Ni/Stainless. This capability allows for the creation of unique high performance multi-material parts for a wide array of engineering applications:
