| description | The invention belongs to the technical field of aluminum alloy, and particularly relates to a high-strength anti-crushing 6-series aluminum alloy profile and a preparation method thereof. The high-strength crushing-resistant 6-series aluminum alloy profile is prepared from, by mass, 0.80%-1.35% of Mg, 0.60%-0.90% of Si, 0.30%-0.40% of Mn, 0.05%-0.20% of Ti, smaller than or equal to 0.20% of Cr, smaller than or equal to 0.25% of Cu, smaller than or equal to 0.25% of Fe and the balance Al and other inevitable impurity elements, the single impurity is smaller than or equal to 0.05%, the sum of the impurities is smaller than or equal to 0.15%, and an AlFeMnSi phase is an irregular and dotted alpha-AlFeMnSi phase; the preparation method comprises the steps of smelting, online refining, casting, homogenizing treatment, cooling treatment, extrusion treatment, online quenching and aging treatment. The 6-series aluminum alloy profile with excellent crushing performance is obtained through proper metal element content |
