TOKYO -- Magnesium prices are rising due to tight supplies from China, by far the world's largest producer of the rare-earth metal, and brisk demand from the auto industry.
Magnesium is mainly used in alloys to strengthen aluminum. While demand for magnesium is growing as automakers work to make their cars lighter, it is also expected to be used in new types of batteries for electric vehicles. If the development of eco-cars proceeds as forecast, magnesium will likely continue to gain luster.
