Abstract

This paper investigates some of the opportunities for magnesium alloys based on magnesium’s attributes, such as excellent die castability and high strength to weight ratio. Barriers to the uptake of magnesium alloys are considered and recent technical advancements outlined including the development of creep resistant alloys, high extrudibility alloys, joining technologies and corrosion performance. Finally issues to do with the life-cycle performance of magnesium alloys are discussed.
