NOVELTY - High-performance lightweight aluminum alloy comprises 10-12 wt.% silicon, 9-15 wt.% magnesium, 1.2-2.5 wt.% chromium, 0.5-0.8 wt.% gel, 10-12 wt.% inorganic fiber, 0.8-1.2 wt.% graphene nanoparticles, and aluminum (remaining amount). USE - Light aluminum alloy for battery shell. ADVANTAGE - The high performance light aluminum alloy has high impact toughness, excellent thermoplastic property, excellent corrosion resistance, and adding gas gel inorganic fiber, has good heat-conducting ability graphene the particle nano particle, local heat insulation ability is strong, relatively high hardness, the whole density is reduced, at the same time, it can ensure the heat insulating property and the thermal conductivity, it effectively reduces the weight of the finished product, which is convenient for the optimized design of the application occasion product.
