FCA US is working on a better way to join magnesium to steel and to aluminum, fusing an expensive lightweight-yet-strong metal to aluminum and tosteel. Steel is strong andrelatively cheap; aluminum is light and somewhat pricey.
Normally, joining dissimilar metals together can result in corrosion,seizure, or other problems, especially as they expand at different rates when heated.
Chrysler’scurrent work was revealed in a presentation to the Department of Energy, where they called their method “Upset Protrusion Joining.” (Thanks, patromigh). Automakers already use magnesium in some places, such as dashboard supports.
One problem of using magnesium, other than cost, ishow hard it is to extinguish magnesium fires, a problem long known to racing circles. (Thanks, Bob Lincoln.)
