Beskar
Beskar is also known as Mandalorian iron. It is a very rare metal that only the Mandalorian armoursmiths know how to shape. It is fairly useless when mined, but when it is shaped by the secrets of the Mandalorians, it becomes a very hard metal, capable of absorbing many hits from blasters and even lightsabers. The Mandalorians make their armour and swords out of it, and in the recent "Legacy of the Force" series, have made fighters and gunships out of the rare metal.
