New low-cost, lightweight magnesium sheet alloy with good formability for automotive applications; 1.5x stronger than aluminum

By mmillikin A research team at Japan’s National Institute for Materials Science (NIMS) and Nagaoka University of Technology has developed a new high-strength magnesium sheet alloy (Mg–1.1Al–0.3Ca–0.2Mn–0.3Zn) that has excellent room-temperature formability comparable to that of the aluminum sheet metal currently used in body panels of some automobiles.

The magnesium alloy becomes stronger than aluminum alloy after a heat treatment, uses only common metals, and could be a low-cost, lightweight sheet metal for automotive applications. A paper on the work is published in the journal Scripta Materialia.

Lightweight magnesium (Mg) alloys have attracted considerable attention for potential applications in the automotive industries. However,
