The opinions in this post are the result of many, many hours of research, including substantial recent research. I've endeavored to reconcile conflicting sources when possible. These opinions do not represent an official Factory or Staff position, and are in no way binding upon starship or tech judges, whose opinion of these materials may vary based on the variety of canon sources available. Also, suggested armor classes are approximations.

One very important point to consider is that some of these are probably only suitable for light or medium armor. For simplicity’s sake, and to avoid confusion with our ten-point scale for armor ratings, I’m going to discuss the physical strength of these materials in a scale from 1 to 5, with durasteel being about a 3. I’m also going to rate them on a five-point scale in terms of weight, with durasteel being about a 3.
On the ten-point scale of armor ratings, 1-4 corresponds to light armor, 5-7 corresponds to medium armor, with 8-10 being considered heavy. Lighter armors allow you to move faster, and if you pick the right lightsabre-resistant material in the right amount, you can theoretically have very light, very fast, lightsabre-proof armor while sacrificing protection against blasters, slugthrowers, explosions and so forth. Many duellists consider that sort of tradeoff worthwhile. Armor does not have to be quality 7-10 to be awesome.
Most of the animals whose scales and hides feature on this list are deadly combatants, often beyond the powers of Jedi and Sith to survive or defeat, let alone kill. Development threads involving these animals would be expected to be very, very substantial, in both post length and post count.
My advice is to pay close attention to this line from the factory rules. "Multiple lightsaber-resistant technologies or substances in one submission will not be approved. This includes beskar/Mandalorian Iron, songsteel, cortosis ore, cortosis alloys, alchemically hardened metal, Eol Sha fireworm scales, lightshields, force fields, phrik, ultrachrome, neuranium and so forth." Leeway has sometimes been given on a case-by-case basis for moderately or minimally lightsabre-resistant materials like armorweave or duraplast, but be wise.
Akk Dog Scales
Physical Strength: 2
Weight: 2
Degree of Lightsabre Resistance: Moderate
Suggested Armor Classes: Medium
Special Properties and Other Notes:
Alchemical Metal (Factory restrictions upcoming)
Physical Strength: 4
Weight: 4
Degree of Lightsabre Resistance: Fully to partially immune. Basic Sith swords can last an entire duel against a lightsabre without significant damage. Some works of alchemy, however, are less durable, while others can be considered untouchable by lightsabre.
Suggested Armor Classes: Heavy
Special Properties and Other Notes: Most items of alchemical metals can absorb lightning to be released later, generally with a successful strike. It should be noted that a true master of alchemy, as in a Master-level alchemical specialist, is probably capable of making wood and bone lightsabre-resistant.
Armorweave
Physical Strength: 1-2
Weight: 1
Degree of Lightsabre Resistance: Variable depending on quality. Dooku’s armorweave cloak could entangle lightsabres, but Zam Wesell’s Mabari armorweave bodysuit provided no significant resistance to a direct hit from Obi-Wan’s lightsabre.
Suggested Armor Classes: Light
Special Properties and Other Notes:
Beskar/Mandalorian Iron (Factory restrictions)
Physical Strength: 4
Weight: 4
Degree of Lightsabre Resistance: Fully immune, in most cases. Micronized beskar crushgaunts can literally hold onto a lightsabre blade. It would burn out a lightsabre’s power pack to cut through a beskad -- a short, heavy sword made of beskar.
Suggested Armor Classes: Heavy
Special Properties and Other Notes:
Cortosis (Factory restrictions)
Physical Strength: 1 (ore), 2 (weave), 3 (alloy)
Weight: 2
Degree of Lightsabre Resistance: Special case. Cortosis ore, like the rock formations underneath the Hand of Thrawn, is very crumbly but will deactivate a lightsabre. Cortosis weave, like the armor of the Jensaarai, is a form of purified cortosis ore, generally backed with, or combined with, layers of another kind of armor; Jensaarai armor (the first canon source to create and flesh out cortosis weave) will deactivate a lightsabre. Cortosis alloys will fully repel a lightsabre with minimal damage to the blade or armor, but will not deactivate it.
Suggested Armor Classes: Any
Special Properties and Other Notes:
Duraplast
Physical Strength: 2
Weight: 2
Degree of Lightsabre Resistance: Low. Heavy duraplast offers some resistance to cutting, comparable to turadium.
Suggested Armor Classes: Any
Special Properties and Other Notes:
Eol Sha Fireworm Scales
Physical Strength: 1 (very hard, but low tensile strength)
Weight: 2
Degree of Lightsabre Resistance: Can repel direct strikes from a lightsabre, but a full-powered strike will crack the scales and render the worm or wearer vulnerable to repeated strikes in the same location.
Suggested Armor Classes: Light to Medium, depending on what material is used for backing
Special Properties and Other Notes:
Force-imbued Blades (not to be confused with weapons protected through the power known as Force Weapon)
Physical Strength: 3
Weight: 2
Degree of Lightsabre Resistance: Fully immune
Suggested Armor Classes: Not suitable for armor.
Special Properties and Other Notes: This is a very ancient forging technique, lost to history, predating even protosabers.
Gadolinium/Non-Ultrachrome Superconductors
Physical Strength: 1
Weight: 3
Degree of Lightsabre Resistance: Equal to ultrachrome; see that entry.
Suggested Armor Classes: Generally not suitable for armor.
Special Properties and Other Notes:
Hijarna Stone/Greater Calama Shell
Physical Strength: 4
Weight: 4
Degree of Lightsabre Resistance: Moderate to High
Suggested Armor Classes: Generally not suitable for armor.
Special Properties and Other Notes: 'Scoundrels' confirmed that Hijarna stone is significantly lightsabre-resistant - even a few inches of it would require several minutes to cut. This may make it more of an option for creative use.
Leviathan Hide
Physical Strength: 4
Weight: 4
Degree of Lightsabre Resistance: Can withstand a direct hit from a lightsabre.
Suggested Armor Classes: Heavy
Special Properties and Other Notes: Good fething luck taking down a Leviathan of Corbos.
Maalraas Bone
Physical Strength: 2
Weight: 1
Degree of Lightsabre Resistance: Moderate.
Suggested Armor Classes: Generally not suitable for armor
Special Properties and Other Notes:
Neuranium (Factory restrictions)
Physical Strength: 5
Weight: 5
Degree of Lightsabre Resistance: Moderate. A lightsabre required several minutes to punch through several inches to a foot of neuranium (Palpatine’s lightsabre being retrieved from the inside of a neuranium statue), but the lightsabre punched through successfully.
Suggested Armor Classes: Generally not suitable for armor (a very thin layer would make for very heavy and tiring armor)
Special Properties and Other Notes:
Orbalisks
Physical Strength: 3
Weight: 2
Degree of Lightsabre Resistance: Can repel direct strikes from a lightsabre.
Suggested Armor Classes: Orbalisk armor, with full coverage, could be considered class 8.
Special Properties and Other Notes: Orbalisks can heal their wearer. However, they cannot be removed without immense risk to your life, even with help from an expert healer, and cause extreme pain.
Phrik (Factory restrictions)
Physical Strength: 4
Weight: 1-2
Degree of Lightsabre Resistance: Can repel direct strikes from a lightsabre.
Suggested Armor Classes: Any
Special Properties and Other Notes:
Songsteel (Factory restrictions)
Physical Strength: 3
Weight: 1-2
Degree of Lightsabre Resistance: Can repel direct strikes from a lightsabre.
Suggested Armor Classes: Medium, variable
Special Properties and Other Notes:
Taozin Flesh
Physical Strength: 1
Weight: 2
Degree of Lightsabre Resistance: Special case. Darth Maul observed that when he struck a large taozin with his lightsabre, the blade appeared to diffuse in the translucent flesh, and the taozin was moderately burned but not cut.
Suggested Armor Classes: Generally not suitable for armor
Special Properties and Other Notes:
Terentatek Hide
Physical Strength: 2
Weight: 2
Degree of Lightsabre Resistance: Moderate.
Suggested Armor Classes: Light
Special Properties and Other Notes: Confers significant resistance to Force effects
Tikulini Hide
Physical Strength: 2
Weight: 2
Degree of Lightsabre Resistance: Moderate.
Suggested Armor Classes: Light
Special Properties and Other Notes: Generally more flexible than terentatek hide
Turadium
Physical Strength: 4
Weight: 4
Degree of Lightsabre Resistance: Low to moderate. Heavy turadium armor and blast doors offer some resistance and take longer to cut than military-grade durasteel.
Suggested Armor Classes: Heavy
Special Properties and Other Notes: Turadium is most commonly used for high-security blast doors, and sometimes to reinforce key sections of elite starships.
Ultrachrome (Factory restrictions)
Physical Strength: 3
Weight: 3
Degree of Lightsabre Resistance: Special case. As a superconductor, ultrachrome can withstand any amount of contact with a lightsabre...until the entire piece melts simultaneously. As a result, Kar Vastor’s ultrachrome vibroshield weapons were large and bulky. Small ultrachrome plates, such as gauntlets and shoulder pauldrons, melt very quickly if they are not in constant contact with other ultrachrome plates.
Suggested Armor Classes: Medium to Heavy
Special Properties and Other Notes:
Vonduun Skerr (Vonduun Crab) Armor
Physical Strength: 3
Weight: 3
Degree of Lightsabre Resistance: Can usually withstand a direct hit from a lightsabre.
Suggested Armor Classes: Heavy
Special Properties and Other Notes: Living Vong biot. Critically allergic to Bafforr tree pollen, usually resulting in a crushing death for the wearer.
Zillo Beast Scales
Physical Strength: 4
Weight: 4
Degree of Lightsabre Resistance: Can withstand a direct hit from a lightsabre.
Suggested Armor Classes: Heavy
Special Properties and Other Notes:
