Metal Composites

At EWI, our focus has always been on helping manufacturers solve real problems and move advanced technologies from concept to production. In 2025, that mission translated into meaningful progress across research, technology development, and knowledge sharing to support industries navigating increasingly complex technical and economic challenges. Throughout the year, our teams worked closely with partners...

Michael Eff, EWI Congratulations to EWI Principal Engineer Michael Eff who has won (along with colleagues Logan Smith and Ian Donaldson) the 2022 Howard I. Sanderow Outstanding Technical Paper Award from The Metal Powder Industries Federation. The paper, Joining of Two-Piece Aluminum Metal Matrix Composite (Al-MMC) Transmission Carrier Via Friction Stir Welding, was selected from...

Metal matrix composites (MMCs) have always been considered “unweldable,” and have been joined mechanically in the past. Now, however, EWI reports that aluminum MMCs can be joined using friction stir welding, a solid-state joining method. This investigation is discussed in Friction Stir Welding of Metal Matrix Composites, written by EWI Senior Engineer Michael Eff. You...
