Abstract: A method for processing aluminum alloy rims including: providing a feed of a plurality of aluminum alloy rims of different compositions, each aluminum alloy rim having a serial number distinguishing that aluminum alloy rim from other aluminum alloy rims; storing in a non-transient computer-readable memory, a plurality of aluminum alloy rim categories; dividing the feed of aluminum alloy rims into a plurality of batches of aluminum alloy rims by, for each rim in the feed of aluminum alloy rims, scanning that aluminum alloy rim to determine the serial number of that aluminum alloy rim; based on the serial number, determining, from amongst the plurality of aluminum alloy rim categories, an aluminum alloy rim category for that aluminum alloy rim, wherein each batch of aluminum alloy rims in the plurality of batches of aluminum alloy rims corresponds to a category in the plurality of aluminum alloy rim categories.
