Method of aluminum-scandium alloy production

A method of producing an aluminum-scandium (Al—Sc) alloy, comprising:

• (a) providing an electrolyte bath comprising a first portion of at least one of ScF3 or AlF3 and a first portion of at least one of LiF, NaF, or KF;
• (b) providing a cathode in electrical contact with the electrolyte bath, wherein the cathode comprises aluminum;
• (c) providing an anode in electrical contact with the electrolyte bath;
• (d) adding a first portion of Sc2O3 into the electrolyte bath;
• (e) reacting an aluminum ion with the cathode;
• and
• (f) applying an electric current to the cathode, thereby reacting a scandium ion with the cathode to produce the Al—Sc alloy, wherein after reacting the scandium ion with the cathode:
• the electrolyte bath comprises ScF3, AlF3, and at least one of LiF, NaF, or KF, and
• the cathode comprises the aluminum and scandium.
