Very easy to oxidize. In the air, aluminum is easily combined with oxidation to form a dense aluminum oxide film (about 0.1-0.2um thick) , the melting point is high (about 2050 ℃), far exceeding the melting point of aluminum and aluminum alloys (about 600 ℃). The density of alumina is 3.95-4.10g/cm3, about 1.4 times that…
