Hfredium was a type of mineral that found use in the building of starships. To create the deep red alloy called havod, it was mixed with chanlon. Several planets were sources of this mineral, including Brosi, Nkllon, Ongary IX, and Shiffrin, along with the Tava Yagen and Pembric asteroid fields where it was mined. During the time of the Galactic Civil War, the typical cost for Hfredium was 110 credits for each kilogram. When Thrawn raided Nkllon and seized Nomad City, Hfredium was one of the minerals that were taken.
