I was surprised the aluminum didn't oxidize/burn/combust when exposed to a naked flame that was hot enough to melt it in the presence of oxygen (air).
Isn't that why they typically use gasses like argon when welding (melting) aluminum, to block the oxygen and prevent it from just burning? I believe they also need to smelt it using a (reductive) electrolytic process for the same reason, instead of just heating it in the presence of carbon like they do with iron ore.
Asphalt is a conglomerate of many different materials meaning it has increased surface area. So the surface of asphalt would start to melt for example at such temperatures but the surface is also at the top which is in contact with the atmosphere and is being cooled just as quickly.
But this is still a good question because if there is enough heat to the point all of the asphalt is heated up to the melting point then it would take more than a day to fully cool again.
ok, fair enough.. my experience is limited to throwing aluminum cans into (hot) fires and burning aluminum foil with sparkler powder. I'll trust a boilermaker to know.
Ive had bonfires up north that burned for 2 or 3 days while clearing my land, white hot with beer cans in it and the beer cans do not melt, they just char and the lattice is weakened. So why dont the beer cans melt in these white hot fires but aluminum wheels did here? One fire is unmoving and the aluminum is engulfed for a couple days and the other by definition is transient. Doesnt make a lick of sense.
I’m with you in it doesn’t all make sense. The fire is having to jump from one object to the next and each object has to reach these high temps but an isolated bonfire being fed doesn’t reach the same temps.

aluminum will melt like that.ive seen and done it. im a retired boilermaker

Looks like the asphalt would get very hot.
you can melt aluminum with a torch.
not sure about the asphalt. was'nt a asphalt-fag . was a boiler-fag...kek

put some grinder dust on an aluminum can and melt it with a torch= thermite. fun times
argon is used with tig and types of mig.but not stick. and with mig it matters what type of wire your using
