Beskar

Beskar, also known as Mandalorian iron, was an alloy used in Mandalorian armor, notable for its high tolerance to extreme forms of damage. The metal was durable enough to withstand a direct blaster shot, and could potentially withstand the slash or glancing blow of a lightsaber, though could be penetrated with a direct stab. A superweapon created by the Mandalorian Sabine Wren and used by the Galactic Empire, called the Arc Pulse Generator, was capable of super-heating the metal to the point that it would burn to a crisp everything it was protecting, as in the case of Mandalorian warriors covered behind their beskar armor.

Description
Beskar was one of the toughest and most legendary metals in the galaxy. The alloy could withstand direct blaster fire. Beskar could also withstand the slash and glancing blow of a lightsaber. The metal could also be reforged to any warrior's liking.

Usage
Beskar was a common material used by the various groups, clans, and houses of Mandalore's people.

History
The Mandalorian Neo-Crusaders wore armor composed of Beskar. Around 501 BBY, Mandalorians continue using the metal in their armor. During the Clone Wars, the Death Watch and the Nite Owls continued to use beskar in their armor. The Death Watch continued using the alloy in their armor when they became part Maul's Shadow Collective and Viceroy Gar Saxon's Imperial Super Commando.

During Mandalore's third civil war, Imperial Governor Tiber Saxon had the Arc Pulse Generator rebuilt and used it against Clan Wren's and House Kryze's warriors. Despite its limited range, the "Duchess" was able to target the beskar in their armor.
