The invention discloses a rare earth aluminum alloy, and a method and a device for preparing the same. The alloy contains at least one rare earth metal of lanthanum, cerium, praseodymium, neodymium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, lutetium, scandium and yttrium, the content of raw earth is 5 to 98 weight percent, and the balance is aluminum and inevitable impurities. The device for preparing the rare earth aluminum alloy is characterized in that: a) graphite serves as an electrolysis bath, a graphite plate is an anode, a tungsten bar is a cathode and a molybdenum crucible serves as a rare earth aluminum alloy receiver; b) the diameter of the tungsten bar is 30 to 55 mm; and c) the anode of the graphite consists of a plurality of graphite plates. The rare earth aluminum alloy, and the method and the device for preparing the same have the advantages that: the alloy has uniform components, little segregation and low impurity content; technology for preparing the rare earth aluminum all
