Embodiment 1
[0017] An oxidation-resistant magnesium-containing aluminum alloy for energy storage at a working temperature of 400-500 degrees. In terms of weight percentage, the composition of the alloy is Sn:8.0wt.%, Mg:29.0wt.%, Si:14.0wt.%, In:0.5wt.%, P:0.1wt.%, Mn:1.0wt.% , and the balance is aluminum. The above-mentioned oxidation-resistant magnesium-containing aluminum alloy for energy storage at a working temperature of 400-500 degrees includes the following smelting steps (under protective conditions): melting the above-mentioned raw materials in a crucible resistance furnace, wherein the active elements are in the form of master alloys join in. In the smelting process, graphite crucible is used, carnallite is used as covering agent, and siderstone is used as refining agent. The crucible is heated to 720-800 degrees to form an alloy melt, and the electromagnetic stirring effect is used to fully stir for about 15 minutes. The alloy melt is kept at 700°C for 15 minutes and then c...
