Symanthite
From Warhammer 40k - Lexicanum
Symanthite is a glittering diamond-hard substance mined by the Imperium. It is used in the construction of armour plating for war machines, as well as high-end wargear and is all but imperious to conventional energy weapons. However armour made from Symanthite can be pierced by blades laced with the substance.[1]
