Abstract
An information handling system (IHS) chassis includes a chassis base. A center portion of the chassis base comprises at least ninety-five weight percent of a first metal element that is one of Aluminum or Magnesium. An edge section of the chassis base extends around the circumference of the chassis base adjacent the center portion. The edge section is comprised of an alloyed material that includes the first metal element and at least five weight percent of at least one second metal element that is selected from the group including Lithium, Titanium, Tungsten, Chromium, Hafnium, Lanthanum, and Ytterbium. The center portion and the edge section may comprise a first layer of the chassis base, and a second layer may be bonded to the first layer. In one example including the second layer, the first metal element is Magnesium and the second layer is at least ninety-five weight percent of Aluminum.
