The invention discloses a 6061G aluminum alloy for a smart phone and a processing method thereof. The aluminum alloy comprises the following components in percentages by weight: 0.50-0.70% of Si, 0.11-0.15% of Fe, 0.15-0.20% of Cu, 0.06-0.08% of Mn, 0.80-1.10% of Mg, 0.11-0.20% of Cr, 0.01-0.03% of Ti and the balance of Al and inevitable impurities. The corresponding processing method comprises the following eight steps: ingot casting, homogenizing annealing, hot rolling, cold rolling, intermediate annealing, secondary cold rolling, solid solution treatment and final aging treatment successively. An aluminum product, with the components of the aluminum alloy, obtained by means of the processing method has an extremely excellent anodizing effect, meets the sand blasting of extremely thin 205-210-mesh zircon sand, is an ideal aluminum alloy material, which is used for 6-series mobile phone appearance part having high demand on strength and anodizing effect, and is wide in market application prospect.
