A process designed to lower the cost of magnesium metal, making it competitive with aluminum, has been an industry goal for over a century. Although magnesium metal makes up millions of today’s lightweight cell phone and laptop cases, its persistently high cost (twice that of aluminum today) has impeded broad, high-volume use in other areas, including the automobile industry. This could soon change, thanks to researchers at INFINIUM, based in Natick, MA, who have developed a low-cost, energy-efficient, zero-emissions process for making this lightweight, strong metal.
