Turn Anodized Aluminum to clean Aluminum

So your cleaning extruded aluminum so you can sell it as clean aluminum at a lower price, or am i missing the point? I thought yards consider aluminum clean as long as no ferrous metal is attached to it. Sounds like your yard is using the logic that a car would be considered dirty steel because the factory painted it. Ie a non metallic coating is applied to the metal. Downgrade is just a fancier way of saying dirty, just another way for the yards scam us.

When a yard sells extruded aluminum it can only have 10% paint/anodized and 10% 60/61 . I work in a yard and we get docked once in a while for excess paint. They call it contamination and the price drops .10 lb. if this happened a lot. We would start docking our customers and separating this material out. So maybe the yards not screwing you but trying to avoid being screwed.
