The Aluminum Association is offering a free online manual that describes in detail the range of commercial technologies that are available for joining automotive aluminum components. It was developed in response to the growing needs of automotive engineers and designers, who are using more aluminum alloys and multi-materials assemblies in their designs.
The multi-chapter Automotive Aluminim Joining Manual was developed in collaboration wiht the European Aluminum Association (EEA) and the US-based Aluminum Extruders Council (AEC).

Your automobile exhaust system, the plastic cup holding your favorite drink, along with many, many other products, rely upon chemical reactions driven by catalysts supported on aluminum oxides. Characterizing these aluminum oxides or alumina has been challenging. Now, scientists at Pacific Northwest National Laboratory (PNNL) and FEI Company obtained an atomically resolved view of the alumina form known as delta alumina. Using experiments and computational approaches, the team showed that the oxide is made up of two crystal forms or variants woven together.
As researchers continue to characterize the structure and behavior of delta alumina and its related polymorph, gamma alumina, “the materials present a lot of questions,” said Dr. Libor Kovarik, PNNL scientist and lead author on the study. “We are working to understand them, particularly the aluminum bonding on the catalysts surface.”

Trains made of aluminum foam, a material that’s stronger, lighter, and better in a crash than fiberglass or regular old metal. Engineers in Chemitz, Germany unveiled a prototype high-speed train cab made with the stuff earlier this year. The composite material is built like a sandwich. Between two pieces of aluminum, each just two millimeters thick, is a 25-millimeter-thick layer of the “foam,” actually a low-density, sponge-like composite of magnesium, silicon, copper and aluminum. And like a good sandwich, there’s no glue. The layers are held together by metallic bonding, the electrostatic attraction of negatively charged electrons and positively charged ions.
