MASS BALANCE APPROACH TO FORMULATE A380.0 ELECTRICAL CONDUIT FITTINGS FROM RECYCLED ALUMINUM ALLOY SCRAPS

This paper describes calculations using the mass balance method on aluminum alloy scraps, including soft drink cans, aluminum engine components, low alloy aluminum materials, and aluminum computer disks, to formulate A380.0 casting alloy. All recycled aluminum alloys from the same source were considered to be identical. Six approaches of mixing by weight percent, with the aid of an X-ray fluorescence technique, were successfully completed. A380.0 electrical conduit fittings were produced using the die casting technique. Mechanical tests including compression, impact, tensile, and suspended load indicated that die cast recycled aluminum alloy conduit fittings under classification 4 (heavy load condition) satisfied the requirements as stated in BSEN 50086-1: 1993.
