Aluminum Car Rims
Aluminum car or pickup rims that have the tires, valve stems, and wheel weights removed. Note: Rims that are aluminum with chrome plating are purchased as cast aluminum, and aluminum semi-truck rims are purchased as aluminum extrusion.
This is aluminum that has been passed or 'extruded' through a die (much like spaghetti noodles are made by squeezing dough through a press). This aluminum must be clean, or free of any and all steel, plastic, foam, wood, glass, tar, other types of metals, etc. Great examples of extrusion are: aluminum window and door framing, ladders, semi truck rims, and certain types of running boards.
This is siding, flashing, fascia, or gutters that are made of aluminum. Factory painted items are okay, however, otherwise it must be clean--meaning any and all insulation or foam backing must be removed and it must be free of steel nails/screws as well as tar/caulk.
This is aluminum that is in sheet form, or aluminum products that have been made by forming or bending a sheet of aluminum. This aluminum must be clean, or free of any and all steel, plastic, foam, wood, glass, tar/caulk, other types of metals, etc. Great examples of sheeting are: aluminum roofing panels, lightweight pots and pans, and lawn chair framing.
Mixed Cast Aluminum
Aluminum products that have been made or 'casted' by pouring melted aluminum in a mold, are considered cast aluminum. Cast aluminum will break under pressure, as opposed to bending like many other types of aluminum. This aluminum must be clean, or free of any and all steel, plastic, foam, wood, glass, tar, other types of metals, etc. Great examples of cast aluminum are: barbecue grill lids/tops, heavy aluminum pots/pans, and aluminum engine/car parts.
Light Aluminum Remelt
This is aluminum that is slightly dirty--meaning that it contains small amounts of plastic, steel, foam, or other components that are not aluminum. To be considered light remelt, the percentage of steel/contaminants to aluminum would be approximately 5% steel (or less) to 95% aluminum. Examples of light aluminum remelt are: aluminum siding that contains steel nails/screws, paper backing, or tar/caulk, storm doors that have steel screws or rivets, ladders with plastic steps or steel rivets, antennae with plastic pieces and steel rivets, and lightweight pots and pans with the plastic handles still attached.
Heavy Aluminum Remelt
This is the dirtiest form of aluminum--meaning that it contains plastic, steel, foam, or other components that are not aluminum. To be considered heavy remelt, the percentage of steel/contaminants to aluminum would be approximately 30% steel to 70% aluminum--the aluminum must outweigh the steel or contaminants. Examples of heavy aluminum remelt are: engines with aluminum blocks and heads, lawnmower engines, heavy aluminum pots and pans with the handles still attached, aluminum engine parts that contain steel, aluminum radiators with the plastic tanks attached, aluminum siding with foam backing, and lawn chairs with intact webbing.
Aluminum foil, screening material, and cans fall in this category. All material must be free of any contaminants, including food. Cans must be rinsed and any paper labels must be removed. Examples are: pop can tabs, cat food cans, and pie tins.
Aluminum shavings are small, thin, pieces of aluminum that are the byproduct of a machining process (much like pencil shavings are created when a pencil is sharpened). All aluminum shavings must be clean, meaning they should contain no steel, plastic, foam, wood, glass, tar, other types of metals, etc. and they should be free from moisture.
