The invention discloses a novel 6063 aluminum alloy material. Rare earth elements are added into the original 6063 aluminum alloy. The novel 6063 aluminum alloy material comprises, based on the weight percentage,0.36%- 0.4% of Si, 0.48% - 0.52% of Mg, 0 -0.35% of Fe, 0 -0.1% of Cu, 0 - 0.05% of Mn, 0 - 0.05% of Cr, 0 - 0.05% of Zn, 0 - 0.05% of Ti, 0.18%-0.22% rare earth elements, 0-0.1% of the remaining impurities and the balance of Al. According to the invention, the content of Mg and Si is controlled within a narrow range. At the same time, cerium-based mixed rare earth elements and alloying element boron are added, which keeps alloy material high strength and high electrical and thermal conductivity; improves machining property and plastic extrusion; and improves production efficiency.
