Automotive Applications for Magnesium Die Castings

Component groups in domestic vehicle designs with significant weight savings potential through conversion to magnesium die castings are reviewed. The criteria for part selection and basic magnesium properties are discussed. Four component groups having a number of parts meeting this study’s criteria were selected--bracketry, pumps and metering bodies, housings and transmission components. Examples of specific parts in each category are given, including estimates of cost savings or cost penalty per kilogram of weight saved.
