Efforts to reduce vehicle weight have mostly focused on aluminum, plastics and composites, but another lightweight material is also getting attention: magnesium. The ninth most abundant element in the universe, magnesium is as strong as steel, but 33 percent lighter than aluminum, 60 percent lighter than titanium, and 75 percent lighter than steel.
Worldwide demand for magnesium is growing steadily at a rate of 3 percent annually, driven primarily by the automotive industry. According to market research firm Ducker Worldwide, the average light vehicle contains some 10 pounds of magnesium, and that amount could triple by 2025.
