Door and window aluminum scrap

The biggest problem with recycling aluminum window and door scraps is that the accessories and connectors of other materials installed on the windows and doors, such as steel, copper or zinc extrusions, require special pre-treatment.

If these substances can be separated from the aluminum alloy and removed,

It is easier to control the composition when remelting the furnace to produce the original alloy ingot.

However, this is difficult to achieve. The current practice is to centrally process the scrap aluminum alloy doors and windows, break them by hammering or cutting, and then separate the other connected materials from the aluminum alloy.
