ALUMINUM ALLOY EXTRUSION AND A METHOD FOR MANUFACTURING THE SAME CAPABLE OF DISPERSING CALCIUM-BASED COMPOUND IN AN ALUMINUM BASE BASED ON THE ADDITION OF MAGNESIUM BASE ALLOY

摘要

PURPOSE: Aluminum alloy extrusion and a method for manufacturing the same are provided to improve the mechanical characteristic of aluminum extrusion by inducing dispersion reinforcing effect and crystalline micronizing effect.;CONSTITUTION: A method for manufacturing aluminum alloy extrusion includes the following: magnesium base alloy is prepared by including calcium-based compound in a magnesium base(S11); the magnesium base alloy is added into molten aluminum(S12); the molten aluminum is casted to obtain aluminum alloy(S13); the aluminum alloy is extruded(S14); and the aluminum alloy extrusion is thermally-treated. The calcium-based compound includes one or more selected from Mg-Ca compound, Al-Ca compound, and Mg-Al-Ca compound. The Mg-Ca compound includes Mg_2Ca.;COPYRIGHT KIPO 2012
