Car and truck wheels with the ISRI term Troma are specifically aluminum grade wheels, but you will also find wheels blended with chrome or made of steel as well. Aside from the different sizes, car wheels being smaller than truck wheels, Troma has different aluminum grades. Car wheels are 356 aluminum, and truck wheels are almost always 6061 aluminum. It is important to separate the 356 and 6061 wheels within the aluminum grades to maximize the value.
Chrome wheels are a different alloy composition; if these are left in with the 356 aluminum wheels, your 356 packages will be downgraded.
Since market conditions are constantly changing, to maximize the value of your car and truck wheels, separate them into specific grades and then clean them by removing wheel weights, stems, inserts. Remove these attachments easily with the right tools. A clean product is worth much more than one with attachments.
Troma Aluminum Auto or Truck Wheels
Shall consist of clean, single-piece, unplated aluminum wheels of a single specified alloy, free of all inserts, steel, wheel weights, valve stems, tires, grease and oil and other non-metallic items. Variations to this specification should be agreed upon prior to shipment between the buyer and seller.
Car rims and Truck rims need to be packaged separately as they are different alloys.
