FIELD: preparation, treatment and manufacture of alloys with beryllium additives. SUBSTANCE: present invention describes treatment of industrial aluminium alloy in semisolid state and pressed powdery beryllium to manufacture products free from beryllides. The claimed method does not involve stirring liquid alloys due to using dispersed or finely divided beryllium particles in admixture with solid particles or with liquid aluminium. Size and shape of beryllium phase (spherical) remains unchanged irrespective of additional treatment. EFFECT: improved properties of the aluminium-beryllium alloys. 26 cl, 5 dwg, 9 ex, 3 tbl
