GM testing industry-first thermal-forming process for lightweight magnesium sheet metal

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.
