Title:
HIGHLY CORROSION-RESISTANT MAGNESIUM-ADDED ALUMINUM ALLOY FOR CASTING
Document Type and Number:
WIPO Patent Application WO/2022/124448
Kind Code:
A1
Abstract:
The present invention relates to a highly corrosion-resistant magnesium-added aluminum alloy for casting, in which, in a manufacturing technology for a highly corrosion-resistant magnesium-added aluminum alloy for casting, silicon (Si), magnesium (Mg), a rare earth element, and the like are added to an aluminum alloy, thus improving corrosion resistance and fluidity. In particular, disclosed is an aluminum alloy obtained by modifying aluminum alloys for casting, such as AC7A, AC7B, ALDC5, ALDC6, ALDC10 and ALDC12 series. The aluminum alloy of the present invention comprises: 0.61-3.0 wt% of magnesium (Mg); 6.0-12.0 wt% of silicon (Si); 0.001-1.5 wt% of copper (Cu); and 0.001-2.0 wt% of cerium (Ce) and lanthanum (La).
