Bavarium

Bavarium is a blue/silver fantasy metal obtained from Bavarite.

It is used for making armour and explosives. The explosives are about as powerful as standard uranium explosives and the armour can give limited time invulnerability.

Bavarium is from Square Enix's third person shooter; Just Cause 3. Bavarium has been used for military applications by the antagonist military. The mineral is used to generate a "Bavarium shield" around vehicles which grants tanks and helicopters temporary invincibility. It is also incredibly explosive as demonstrated by the military manufacturing warheads tipped with bavarium, increasing their destructive capability immensely.
