Aluminum Dross Processing :: Total Materia Article

Aluminum dross, a byproduct of the aluminum melting process, is a mixture of aluminum, its oxides, the oxides of alloying elements and less frequently halogenides, carbides and nitrides. Dross has some good benefits, especially considering tension strength and depending on further conditioning steps can be very useful further on.
