Recent developments in Magnesium alloys, processing techniques and corrosion protection schemes are reviewed.

The casting alloy WE43 is detailed, data being presented which shows that it compares favourably with Aluminium based casting alloys on a strength to weight basis. In addition its intrinsic corrosion characteristics are shown to be similar to those of Aluminium base alloys.

A counter - gravity casting process, specifically designed to make higher quality, thin-walled Magnesium alloy components is described together with property data indicating the improvements obtained.

Also discussed are the ongoing developments in Metal Matrix Composites and Rapid Solidification technologies, showing the benefits offered by these processing routes.

Finally current corrosion protection schemes are reviewed and their overall cost effectiveness discussed.
