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.
