The Green Optimistic reported that magnesium sheet metal may play a key role in fuel efficiency for auto makers.
As quoted in the market report:
GM’s new magnesium thermo-formed panels are three or four times more expensive, but are 75% lighteran steel panels and 33% lighter than aluminum panels. “Every gram of weight reduction matters when it comes to improving fuel economy,” said Greg Warden, GM executive director for global vehicle body engineering. “Being able to replace heavier metals with one of the lightest will help us deliver better fuel economy to customers around the world while also still providing the safety and durability they expect.
