NOVELTY - Preparing thin-wall aluminum alloy involves taking 0.1-0.25 wt.% copper, 0.15-0. 2 wt.% manganese, 1.5-3 wt.% magnesium, 0.01-0.05 wt.% zinc, 0.02-0.2 wt.% chromium, 0.25-0.35 wt.% titanium, 0.5-1 wt.% silicon, 0.2-0.35 wt.% iron, 5-8 wt.% graphene and balanced amount of water. The method involves immersing graphene in liquid furan resin, taking out and drying. The surface of graphene is electroplated with copper, after washing, washing and drying with deionized water. The copper-plated graphene and the powder of the above components are thoroughly mixed uniformly according to the above mass percentage, and compacted to obtain a thin-walled aluminum alloy base block. The thin-walled aluminum alloy base block obtained is heated in a crucible to be melted to obtain a thin-walled aluminum alloy melt. USE - Method for preparing thin-wall aluminium alloy. ADVANTAGE - The method enables to prepare thin-wall aluminum alloy with good wear-resisting property. DETAILED DESCRIPTION - The aluminum alloy melt obtained is heated to 700-730 degrees C and refined. Degassing, slag removal, cooling to 630-650 degrees C for metamorphic treatment, slag and pouring into the preheated metal type for rapid cooling, forming.
