OUT OF CHARACTER INFORMATION
Aluramic is a ceramic composite composed of aluminium, oxygen and nitrogen. The secret of its' construction and developmental history during the Gulag Plague and samples of the transparent material were located aboard an adrift vessel which appeared to the attendant Defenders to be a colony ship staffed entirely by hostile security droids in the deceased's colonists absence which were quickly dispatched. The League of Sanctified Steel set about testing the then alien material and when it performed admirably in a hardness and flexure test the Order of Artisans began researching its' chemical composition and properties in 439 ABY and attempted to reverse-engineer the material. After approximately ten years of constant work and research which consisted of procuring more evidence of its' development history the Order's chemists and metalsmiths succeeded in determining the material's chemical composition and the necessary treatment processes required to reproduce its' nearly mythological levels of toughness.
Aluramic can be used in a variety of applications including; Infrared-optical windows, Visible-light Windows, Near-ultraviolet windows, laser communications, plates, domes, rods, tubes and other forms commonly seen among other ceramic materials constructed using ceramic powder processing techniques. The Aluminium concentration varies considerably which also affects transparency, this variation ranges from 30% to 36%, at 36% the material has approximately 80% transparency and around 90% transparency at 30% this inflicts the bulk and shear moduli negligibly. As part of the hardening treatment processes the Aluramic is subjected to grinding and polishing firstly to improve clarity, transparency and surface hardness and its' other mechanical properties, in terms of melting point the material should melt at about 2,200 Degrees Celsius in an inert atmosphere.
- Intent: Create a transparent and yet weapon resistant material to be used ideally in armor submissions and other protective technology.

- Extreme hardness: The transparent ceramic is extraordinarily hard and 41mm (1.6 In) of the material is capable of surviving sustained kinetic impacts carrying in excess of 20,200 Joules of kinetic energy leaving it easily capable of shrugging off firearm or slugthrower munitions which would be anything less than a high caliber heavy machine gun firing armour-piercing rounds.
- High melting point: Due to its' chemical and physical properties combined with the high quality of manufacture provided by the League of Steel the Aluramic possesses a melting point of approximately 2,200 Degrees Celsius which is sufficient to strongly resist repeated impacts from energy weapons.
- Radiation hardened: Due to its' physical and chemical properties the Aluramic successfully reduces the effective amount of ionizing radiation that passes through its' structure by approximately 99.9% making it a particularly attractive candidate for use in personal armor and as radiation shields in medicinal applications.
- Transparent: The Aluminium, oxygen and nitrogen based ceramic composite is at minimum if not more than 80% transparent depending on its' aluminium composition which ranges from 30 to 36%. It is transparent on the visible light, near-ultraviolet and medium infrared spectrum of the electromagnetic spectrum.
- Diminishing returns: While its' material properties are impressive in the land of armor Aluramic produces diminishing returns when extremely thick, while it is light it is simply not pragmatic to construct armored vehicles or armor out of 82mm of Aluramic even if it would successfully resist high-velocity armor-piercing cannon-caliber rounds. Additionally, the transparent Aluramic is resource and time intensive to produce in such quantities.
- Ionic conductivity: With most materials when the temperature is elevated their chemical and physical states change and Aluramic is no different, at elevated temperatures its' constituent particles and atoms behave in a way that makes the Aluramic amenable to the passing of ions and other charged particles. The inverse is true for its' thermal conductivity, the hotter it gets the less conductive the Aluramic becomes. When used in a personal armor application as a visor, the Aluramic at temperatures approaching boiling point it can pose a hazard for a soldier and allow for the passage of the likes of force lightning or electric current.
- Repair difficulty: As a ceramic once its' yield strength has been exceeded the Aluramic is difficult and beyond economic to attempt repair preventing or discouraging its' widespread use in the likes of warship and vehicle hulls. Helmets which have an Aluramic visor shattered must be totally disassembled and the ceramic composite carefully removed before a replacement can be settled inside.
- Not high enough: Unfortunately despite its' impressively high melting point Aluramic does not possess the necessary chemical or physical properties to successfully resist the likes of weapons such as lightsabers, plasma cutters, plasma torches or electro-plasma weapons which can cleave through even the hardiest materials save for the rare and exotic.
