Throughout the Star Wars franchise, beskar is extremely blaster-resistant, though there are some exceptions to this. The Mandalorian and Death Watch warriors in Star Wars: The Clone Wars and Star Wars Rebels are shown being killed by single blaster bolts, which penetrate their beskar armor.
Formerly wielded by Magistrate Morgan Elsbeth, a beskar spear rings with distilled purity when struck against other beskar. Not only can it withstand lightsaber blows; it is capable of piercing Mandalorian armor.
The purest form of beskar was capable of repelling the strikes of a lightsaber for brief amounts of time, and could withstand direct blaster fire. Pure beskar could still be damaged by weapons also made out of beskar; because of this, making weapons out of beskar was considered illegal by the Children of the Watch.
This has not been confirmed by canon yet, but it is the likely reason, seeing as the only weapon that could absolutely destroy beskar - or at least the person wearing it - is the Arc Pulse Generator.
It is a special type of material that is resistant against lightsabers. Nothing can penetrate it, nothing can destroy it. This is why Mandalorians have become quite a unique group within the Star Wars universe, being one of the great rivals of the Force-wielders of the galaxy.
Although beskar is more vulnerable to blaster bolts, a melee weapon being capable of piercing beskar armor is likely extremely rare, making The Armorer and Djarin's decision to melt it down in The Book of Boba Fett is understandable, as it posed a greater threat to them that even a lightsaber, which was notoriously ...
Beskar is supposedly resistant or proof to lightsabers, but is it strong enough to prevent itself from being crushed by someone using the force? Beskar is an extremely tough metal. It's unable to be affected by blaster bolts and even lightsaber strikes.
However, despite its strength, the armor doesn't offer total immunity to harm. Repeated damage can wear down and eventually break beskar, and beskar weapons are incredibly effective against it. There is also the risk of concussion, which can make even non-piercing blows fatal.
Cherished for its incredible strength and durability, beskar was notable for being able to withstand blows from even a lightsaber, and was commonly thought to be nearly indestructible, making beskar more prized than durasteel or cortosis.
These melee weapons, including electro-bisentos (glaive), Bilari electro-chain whips (incredibly flexible sword), and vibro-arbir blades (double sided weapon), were not only capable of deflecting lightsaber blows, but they could also puncture straight through Beskar armor, as shown in Mandalorian Season 3 when a team ...
Boba Fett's armor was a suit of customized Mandalorian armor worn by Boba Fett, a human clone who became a bounty hunter. The armor was made from beskar. It consisted of a helmet, a cuirass, vambraces with retractable wrist blades, and a Z-6 jetpack.
The material can be easily shaped and melted into shapes, worked with heat and hammering. What's more, it can withstand blasters and lightsabers, so it's safe to assume that it's fireproof. So technically, beskar should contain an inorganic fiber that doesn't burn.
But the closest thing we would have in real life is probably Tungsten: Now there's actually an alloy called Tungsten titanium carbide which is supposedly a mixture of the two up above.
Mandalorian armor forged from beskar can withstand blaster bolts, nearly impenetrable protection that made the warrior class difficult to defeat at the height of their power. After the fall of the Empire, the nearly indestructible steel is harder to come by.
We saw a Beskar-made rod wielded by Din Djarin against Moff Gideon. Gideon was wielding Darksaber, but he could not cut through the rod. The Mandalorian Beskar weapons and armors are the reason why Jedis could not easily win in the Jedi/Mandalorian war.
Pure beskar is damn near indestructible by most sources. It'll deflect pretty much everything that hits it, but that doesn't mean that being hit is going to be pleasant, as you're still dealing with the force behind those hits.
Jango Fett's armor was partly made of durasteel, and General Grievous had some parts of his body made of this material. Darth Vader's armor was mostly made of durasteel, as was Boba Fett's before he upgraded during the Second Galactic Civil War to armor made of beskar.
The plasma that comes from a lightsaber blade: Can cut through pretty much anything it touches. exceptions include Beskar, or Mandalorian iron, the strongest metal in the galaxy, as well as the scales of a Zillo beast.
Darth Vader's armor was made of materials including obsidian, plasteel, durasteel, and plastoid; although its design inspired fear and symbolized the strength of the Galactic Empire, it was also critical to Vader's survival after his defeat on Mustafar.
Beskar armor can resist the first few blows of a lightsaber, but repeated strikes at the same spot will damage the armor though. Beskar was resistant to lightsaber strikes to a large extent. The reason Mandalorians adopted beskar was, during the Jedi-Mandalorian Wars, that it could take several lightsaber blows.
Beskar is known to be able to withstand direct lightsaber hits. Lightsabers can withstand force lightning. So if beskar can withstand lightsabers, and lightsabers can withstand force lightning, then by the process of elimination, Boba's armor could probably withstand force lightning.
It's possible that Gideon used the pure beskar from a fallen Mandalorian in order to craft his own helmet from scratch, or he just used it as is. It's also a possibility that Esposito's villain is using the same general helmet of a dead Mandalorian but made some alterations to it along the way.
