Engineers have found a way to weld AA 7075, an aluminum alloy developed in the 1940s that was thought to be impossible to weld together. The alloy has always held promise for use in the manufacture of cars but for its one fatal flaw. Now, however, the UCLA Samueli School of Engineering is infusing titanium carbide nanoparticles into AA 7075 welding wires, which are being used as the filler material between the pieces being joined.
