Caesium - Wikipedia
Caesium forms alloys with the other alkali metals, gold, and mercury (amalgams).At temperatures below 650 C (1,202 F), it does not alloy with cobalt, iron, molybdenum, nickel, platinum, tantalum, or tungsten.It forms well-defined intermetallic compounds with antimony, gallium, indium, and thorium, which are photosensitive.
