A method for refining admixtures of iron, titanium and zirconium out of aluminium alloys consists in melting an aluminium alloy together with metallic additions - chromium and/or manganese as well as with molybdenum and/or tungsten and/or vanadium, these additions being used in such a quantity so as to ensure that the weight ratio (Mo and/or W and/or V + Cr and/or Mn) : (Fe + Ti + Zr) is equal to 0.2-2.0, and the weight ratio (Mo and/or W and/or V) : (Cr and/or Mn) is equal to 0.03-10, after which the obtained melt is cooled to 590-700 DEG C and filtered within said temperature interval. |
