Aluminium is alloyed by adding alloying ingredients to the molten metal in an intermediate treatment vessel or ladle rather than as at present in a casting furnace. If several ladles are used to supply the casting furnace the alloying ingredients may be added to some but not all of them. A preferred order of addition of alloying ingredients is i) AlF₃ to reduce unwanted Na Ca and Li ii
