Calcium

Calcium is used as an alloying agent for aluminum, beryllium, copper, lead, and magnesium alloys to improve mechanical properties and grain structure.

Calcium metal targets are used in sputtering processes to create thin films for research in organic electronics and as reactive layers in specialized thin-film stacks.

Calcium is used as an evaporation material in the fabrication of organic light-emitting diodes (OLEDs) to serve as a low work function electron injection layer.
