Please advise me, how much can the price difference between aluminum profiles produced by waste aluminum and recycled aluminum and aluminum profiles produced by ordinary aluminum bars be?

Your question is very contradictory. Looking back, waste aluminum was drawn into aluminum rods only to be melted into molten aluminum in the furnace. Of course it's expensive, but it also depends on what kind of pole you want. Commonly used 6063T5 and 6065T5 are probably 15000. This kind of rod is used to produce radiators and alloy rods, while ordinary doors and windows are extruded from aluminum-magnesium rods, that is, waste aluminum is being melted and then drawn into rods.
