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.
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 could protect the wearer from blasters and even lightsabers. The famed Mandalorian bounty hunter and foundling Jango Fett wore customized armor made of beskar alloy, which was later inherited by his cloned son Boba.
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.
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.
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.
Boba Fett's armor was previously stated to be made of durasteel. However, "Chapter 14: The Tragedy" of The Mandalorian retconned the Fett armor into being made of beskar.
No, Captain Phasma's armor, as well as her blaster, is actually made from Chromium. If Phasmas armor was actually made from Beskar it would not have been able to break like it did in her duel with Finn in on the Supremecy.
Notably, the Dagoyan Masters of Bardotta regarded the Jedi as thieves and kidnappers because of that practice. Some Mandalorians, most notably members of Death Watch, held a grudge against the Jedi for their perceived crimes against Mandalore during the Mandalorian-Jedi War.
Mandalorians View Beskar as Intrinsic to Their Culture
All of Gideon's Stormtroopers were wearing beskar armor, and Moff Gideon's Dark Trooper armor was also made of beskar. The fact that Gideon's armor was beskar was an insult in and of itself.
While there is no in-universe canon explanation to justify that change in the Jedi's clothing, the Star Wars Expanded Universe established that wearing bulky armor could slowly interrupt the Jedi's connection with the Force.
The Darksaber was an ancient black-bladed lightsaber. It had a unique blade that was shorter than that of most lightsabers, and shaped like a traditional sword. Its overall profile was distinctly Mandalorian with an angular pommel, hand guard, and slit-shaped blade emitter, all of which was made out of beskar.
Could be any number of reasons ranging from faulty surge protection anodes, to Starkiller and Palpatine having vastly different current frequencies and voltages in their force lightening.
Kylo Ren's obsession with Vader is clear, but Star Wars never explained how he acquired the helmet. It is speculated that he may have found it himself on Endor, or it could have been passed down to him by Supreme Leader Snoke.
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.
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.
In contrast, Din Djarin's armor was made from pure beskar, earned through the bounty on Grogu. This made Djarin's armor rare and even more durable than normal Mandalorian armor, allowing it to stay shiny and undamaged even when he walked into a barrage of blaster fire.
The Mandalorian makes a point of saying that he finds pure Beskar, which is the metal in its best and strongest state. Beskar can only be found on Mandalorian worlds, which makes it very rare. This means that a lot of Mandalorians before the Night of a Thousand Tears didn't have full sets of pure Beskar.
Jango Fett was a Mandalorian. He got the distinctive Beskar steel armor and attached weapons systems the same way every other warrior of the clan did; he earned it. Jango fought in the Mandalorian Civil War as a Mandalorian Commando. He was a foundling, just like Din Djarin long after him.
Darth Vader's armor isn't made of beskar, but of durasteel, allowing mobility and absorbing energy from lightsaber blows. Obsidian in the armor supercharged Vader's dark side power, turning anger into a power source.
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.
Also, due to the unique properties of the micronized Mandalorian iron, also known as beskar, the user of a crushgaunt could easily catch and hold a lightsaber blade in his grasp, or summarily block an opponents blade.
