Named for the term used by scientists to refer to a theoretical perfect material for a project, Unobtainium is used as a classification for the valuable metals and elements harvested by SHX Corp. The most common Unobtainium is Type 3, a highly malleable, yet strong, metal. Unobtainium type 4 is a room temperature superconducting metal and, due to its many uses, is highly sought after; losing a Type 4 mining vessel is a large blow to any mining corporation
