Durasteel

Durasteel was an incredibly strong and versatile metal alloy, created from carvanium, lommite, meleenium, neutronium, and zersium. It was capable of withstanding blistering heat, frigid cold, and monumental physical stress, even when very thin. Because of these properties, durasteel was used for almost everything, from smelting pots for other less hearty metals, to spacecraft hulls. Despite that, however, it could still rust. Durasteel containers were commonly seen throughout the Galaxy.
