Chromium

Chromium, also known as chrome, was a rare and valuable elemental metal that could be used as currency as well as plating for a starship. In the Naboo culture, a ship plated with chromium signified the presence of royalty. Even after stepping down as Queen of Naboo, Padmé Amidala continued to travel in ships fully clad in chromium. Chromium was mined from one of Naboo's moons.

To resist interdimensional shift stress, hyperdrive systems typically required a specific alloy of chromium and titanium. Pure chromium had the ability to block communications.

The armor worn by Captain Phasma of the First Order was coated in chromium salvaged from a Naboo yacht once owned by Emperor Palpatine. The polished finish of that armor was capable of reflecting certain harmful radiations and blaster fire-proof. Phasma's blaster rifle was also coated in chromium. Lando Calrissian had a pair of SE-14r light repeating blasters plated in brushed chromium.

In the Anoat sector, the Trandoshan Brask, who operated a requisitions depot on Burnin Konn during the Iron Blockade, offered select inventory in exchange for chromium.

Despite its gold-like shine, C-3PO's hull actually had a chromium finish.

Chromium features in the non-canon video game Star Wars: Galaxy of Heroes as the middle tier datacard pack.
