General
Motors is testing an industry-first thermal-forming process and proprietary
corrosion resistance treatment for lightweight magnesium sheet metal that will
allow increased use of the high-strength alternative to steel and aluminum.
Magnesium weighs 33% less than aluminum, 60% less than titanium, and 75% less
than steel.
GM wants to
expand its use of low-mass parts on vehicles around the world and will pursue
licensing opportunities related to this novel technology. The goal is for
suppliers to be able to use the process to provide significant amounts of
magnesium sheet that will trim pounds from vehicle mass.
