More metal competition: GM China casts magnesium prototype part


The General Motors (Detroit, MI) China Advanced Technical Center in Shanghai has announced that its micro-foundry and formability lab successfully completed the initial low-pressure casting of a magnesium part, a milestone in lightweight automotive materials research.

The ATC team carried out the melting and casting of magnesium ingot materials and developed a prototype magnesium alloy control arm. The part, which is used in vehicle chassis systems, is 30 percent lighter than a similar part made from aluminum. Lighter parts mean improved fuel efficiency for consumers whose cars in the future will be made up of more magnesium materials according to GM.
