Google "aluminum foundry fire", there is plenty of examples. It does not burn easily but once aluminum has ignited it can continue to burn under normal atmospheric conditions, especially if it begins to melt and boil.

Yes, what I've found indicates that aluminium burns when it boils, which is at 3073 °C, which doesn't happen in normal fires (house, car, forest fires), which is why it's safe in normal fires. It is melting at 660°C, at which point it doesn't burn unless perhaps if finely distributed by way of pressured air bursts or similar. Sparks are hotter than 3073°C, but usually they don't ignite aluminium either--there not being enough aluminium vapour to sustain the reaction. I've done what you said and googled, but have not found a case that indicates non-dust aluminium was burning. https://www.readingeagle.com/2022/04/19/reamstown-fire-aluminum-foundry/ https://www.readingeagle.com/2022/04/19/reamstown-fire-alumi... : Looks like a dust fire.
