Mandalorian iron

Mandalorian iron, known as beskar in Mando'a, was a nearly-indestructible metal alloy first used by the Mandalorians.

While the material was nearly indestructible, it was extremely heavy. Because of this, Mandalorian iron weapons were useless except when attached to a cloth suit and worn as heavy armor. Creating an alloy of Mandalorian iron was exceedingly difficult and known to few non-Mandalorians. Furthermore, the iron is resistant against the blade of lightsabers.
