The advantageous aspects of semi-solid-state metal (SSM) processing were initially discovered by MIT researchers in the early 1970s. The two pertinent processes are rheocasting and thixocasting routes. The temperature of the melt is crucial in determining the optimum point between liquid- and solid-state. SSM processing is most efficient when done at a certain point within the […]

Sapa is making the Design Manual available as a downloadable app for iPhone and iPad users, available in the Apple Store (an android version is forthcoming). The app offers a new channel to reach architects, designers, engineers, and students, who are eager to learn more about aluminum and aluminum profiles.The Design Manual is a strong […]
The globalization of the aluminum industry has made it imperative that universal alloy and temper designations be adopted worldwide. Already, there is an international accord regarding the designation and composition of aluminum and aluminum alloys, published by The Aluminum Association in TEAL SHEETS 2009. However, there still is no international accord on designation and registration […]
As screw fasteners are so often used in aluminum structures, the structural integrity of joints made with these fasteners are highly dependent on proper design guidelines. The Hydro Extrusion Design Manual 2009 and The Aluminum Association’s Aluminum Design Manual 2005 present general design guidelines for mechanical connections. The Hydro Manual includes joining guidelines for longitudinal […]
Dr. V.I. Johannes and C.W. Jowett’s paper, “Temperature Distribution in Aluminum Extrusion Billets” (referenced in “Homogenization of Aluminum Alloy Extrusion Billet, Part III” in the April 2009 issue of LMA), has been updated by Johannes with corrections to the equations that originally appeared in the paper in the Proceedings of the Sixth International Extrusion Technology […]
