Instead, most of the material is nearly-pure Al, while some small regions are Li-rich.¹ (These small regions are called precipitates and they are responsible for giving Al-Li alloys much better properties for aerospace applications relative to pure Al. We'll learn more about the alloying process and about precipitates later in the course.)
