Notes:
Praseodymium is used in special alloys and glasses. It is moderately soft,
ductile, and malleable, and is a silvery color. Small amounts of praseodymium
are used in a rare-earth alloy used to make cigarette lighter flints and high-
strength, low-creep magnesium alloys used for jet-engine parts.
