An alloy containig lanthanide metal, iron, traces of  S,C,Ca and Al is mischmetal.
It is used in Mg-based alloy to produse bullets, shell and lighter flint.

Mischmetal (from German: Mischmetall - "mixed metal") is an alloy of rare earth elements. It is also called cerium mischmetal, rare earth mischmetal or misch metal. A typical composition includes approximately 50% cerium and 25% lanthanum, with small amounts of neodymium and praseodymium. Its most common use is in the ferrocerium "flint" ignition device of many lighters and torches, although an alloy of only rare-earth elements would be too soft to give good sparks. For this purpose, it is blended with iron oxide and magnesium oxide to form a harder material known as ferrocerium.

Misch metal alloyed with iron is the flint  in cigarette lighters and similar devices. Misch metal is also used as a deoxidizer in various alloys and to remove oxygen in vacuum tubes.
