Department Introduction

Department of Magnesium is developing key technologies for high-performance and high value-added magnesium alloys as the lightest structural metal. Especially, we are focusing on development of new alloy systems such as stainless, eco-friendly and non-flammable alloys, high-strength alloys for casting and extrusion, high-formability sheets and process-engineering development. Based on this, we are strengthening cooperation with various domestic and foreign institutions and companies for practical applications and promotion of magnesium material and parts industry.
