ALUMINUM ALLOY HAVING IMPROVED OXIDATION RESISTANCE, CORROSION RESISTANCE, OR FATIGUE RESISTANCE, AND DIE-CAST MATERIAL AND EXTRUDED MATERIAL PREPARED BY USING THE ALUMINUM ALLOY

摘要

Provided are an aluminum (Al) alloy prepared environment friendly and having excellent oxidation resistance properties, and a method of preparing the Al alloy. An oxidation-resistant Al alloy according to an embodiment of the present invention is casted by adding a magnesium (Mg) master alloy, in which a calcium (Ca)-based compound is distributed in an Mg matrix, into molten Al. An Al matrix includes the Ca-based compound. The Al alloy has superior oxidation resistance to a corresponding Al alloy not including the Ca-based compound.
