摘要
PROBLEM TO BE SOLVED: To obtain an Al-Mg-Si based aluminum alloy extrusion material for machining having excellent machinability.;SOLUTION: This Al-Mg-Si based aluminum alloy extrusion material contains, by mass, 1.5 to 7.0% Si and 0.5 to 1.0% Mg and has a Charpy impact value of 6.0 to 9.5 N.m/cm2. If required, the aluminum alloy may contain (1) 0.1 to 1.0% Cu, (2) one or more metals selected from Mn, Cr and Zr respectively by 0.05 to 0.5% and (3) 0.01 to 0.1% Ti.;COPYRIGHT: (C)2002,JPO
