aluminium evaporates (turns into a gas) at around 2200°C

Aluminium nonetheless resists corrosion really properly

“Provided the proper circumstances, a thin film of corrosion items can kind on a metal’s surface spontaneously, acting as a barrier to additional oxidation. When this layer stops growing at significantly less than a micrometre thick below the conditions that a material will be employed in, the phenomenon is recognized as passivation (rust, for example, normally grows to be considerably thicker, and so is not regarded as passivation, since this mixed oxidized layer is not protective). Even though this effect is in some sense a house of the material, it serves as an indirect kinetic barrier: the reaction is usually fairly rapid unless and till an impermeable layer types. Passivation in air and water at moderate pH is observed in such components as aluminium, stainless steel, titanium, and silicon.”- Wikipedia
