| Metallics | Description: | Place of Origin: |
| Meleenium | Hard-cast substance used for most commonplace objects. | Af'El |
| Neutronium | Powdery substance that has no use except when alloyed with another metal such as Crovite and then becomes an excellent, reliable material. | Widespread |
| Durasteel | Fusable, refined metal-alloy used in ship and vehicular construction. Usually comprised of meleenium and neutronium. | Industrial planets |
| Lommite | Crystal-like substance, essential component in transparisteel. | Elom |
| Doonium | Reinforcing plating used on Imperial-built craft. | Roonadan |
| Plastoid | Workable material used for body armor and shaped objects. | Widespread |
| Alzoc Pearl | Crystalline substance essential in Impervium. | Alzoc III |
| Crovite | Commonplace substance used in alloys and ordinary items such as datacards and pins. | Widespread |
| Olumite | Unique, flaky metallic that has to be refined several times over to produce a reliable material. When finished, it feels fiberous to the touch, more like an organic. | Caspian sector |
| Impervium | Refined Ceramic used for Stormtrooper Armor, defelection barricades, high-performance speeders, and battle droids. Requires alzoc pearl, crovite, and plastoid | Imperial planets |
| Zersium | Highly conductive metal used for all electronics, droids, and motivators. | Asteroids |
| Niikron | Film-like, electrically unstable filament that when sparked by a charge from a motivator emits a pulse of energy. Used in sensor arrays and detection equipment. | Electronic planets |
