There’s a “real horse race” at General Motors between new magnesium alloys and carbon-fiber reinforced plastics for use in load-bearing structural applications of future car platforms. That comment was made in an exclusive Design News interview today with Mark Verbrugge, the director of GM’s materials and process lab. For the moment, magnesium is leading because of the successful use of a new Norsk Hydro magnesium alloy in the engine cradle of the Corvette Z06, The cradle provides a 35 percent weight savings over the previous aluminum structure. “There are only about 10 pounds of magnesium in a car now,” says Verbrugge. “There’s a lot of bandwidth there for magnesium to go after.”
