... the production of a greater proportion of aerospace castings in the relatively new zirconium types. Although the Mg-Al and Mg-Al-Zn alloys are generally easy to cast, they are limited in certain respects. They exhibit microshrinkage when sand cast, and they are not suitable for applications in which...
