ALUMINIUM ALLOY WITH IMPROVED RESISTANCE AGAINST OXIDATION, CORROSION RESISTANCE OR IMPROVED FATIGUE RESISTANCE, AND PRODUCT OUT OF THIS ALLOY RECEIVED BY DIE CASTING OR BY EXTRUSION Russian patent published in 2015 - IPC C22C21/06 C22C1/03 

FIELD: metallurgy.

SUBSTANCE: invention relates to aluminium alloys received without harm to environment and having good resistance to oxidation. Method of the product manufacturing out of aluminium alloy includes production of the magnesium alloy by addition to the melt of the magnesium particles based on Ca with size 0.1-500 mcm in amount of 0.001-30 wt %, addition of the produced alloy in the aluminium melt in amount of 0.0001-30 weight parts per 100 weight parts of Al, melt holding or mixing for time period from 1 to 400 minutes, and further extrusion or die casting of the produced alloy. At that the produced aluminium alloy contains from 0.1 wt % to 15 wt % of magnesium and calcium in amount from 0.0001 weight parts to 10 weight parts per 100 weight parts of aluminium, at that calcium is contained in aluminium matrix in form of at least one of compounds selected from Mg₂Ca, Al₂Ca, Al₄Ca, (Mg,Al)₂Ca.

EFFECT: increased alloy resistance against oxidation.
