Title:
ALUMINUM ALLOY FOR HIGH-TOUGHNESS CASTING AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/139007
Kind Code:
A1
Abstract:
The present invention relates to an aluminum alloy for casting and a manufacturing method therefor, and in a technique for manufacturing an aluminum alloy for high-toughness casting, silicon (Si), a rare earth element and the like are added to an aluminum alloy to improve strength, toughness, corrosion resistance and releasability while maintaining the flowability of an alloy for casting. Specifically, disclosed are: an aluminum alloy that is superior to AC4A- and ALDC3-based alloys, which are aluminum for casting; and a manufacturing method therefor. The aluminum alloy of the present invention comprises 8.0-11.5 wt% of silicon (Si), 0.10-0.60 wt% of magnesium (Mg), 0.0001-0.80 wt% of manganese (Mn), 0.0001-0.60 wt% of copper (Cu), 0.0001-0.50 wt% of zinc (Zn), 1.3 wt% or less of iron (Fe), 0.3 wt% or less of titanium (Ti), and a rare earth element such as cerium (Ce) and lanthanum (La).
