I suppose the molten metal around the cars must be aluminum. It melts at 1221 F.
Or body seam filler, of a tin solder alloy. I have some for doing body panel work, it's a non-lead substitute that melts at half that of aluminum, maybe around 600 F. Hit it with a butane or propane torch and it easily flows into puddles like that in the picture. But those pictures show evidence that those cars experienced extremely hot temperatures that could easily melt aluminum as you say. Interesting to see the tire steel strands left over after the rubber tires vaporized.
You might be right, but I’ve never seen melted aluminum yhat looked like that.
It looks like lead. What they used to cover seems in body welds.
Also lead from the batteries. There is something like 20 lbs of lead in a car battery.
That was a well-written article.
Interesting photo of all of the burned out cars. Except three right in the middle of a row - Yellow, blue and white I think they were. Beat up - but not burned. Weird.
