Short answer: Aluminium melts at a much lower temperature than steel, oxidises quickly and loses metal as dross if it is thin or dirty, and its many alloys have to be kept apart to produce the right product, so remelters prefer clean, sorted, sizeable aluminium and pay less for thin, painted or mixed material that loses more metal in the furnace.

Aluminium melts at a much lower temperature than steel, so it needs different furnaces and practices.
Oxidation
Thin and dirty aluminium oxidises quickly, which wastes metal.
Alloy sorting
Different aluminium alloys serve different purposes, so mixing them reduces value.
