About aluminium scrap
The cleanest aluminium is extrusion: window and door sections, partition framing and architectural profiles. Sold free of glass, rubber gasket, screws and steel inserts, it is the top grade. The same sections with glass panels and steel hinges still attached are bought at a blended rate because we absorb the stripping work.
Cast aluminium — engine parts, pump bodies, cookware and machinery castings — melts differently from extrusion and is graded separately. Alloy wheels sit in their own category and are among the better-paying aluminium grades, provided the tyre and steel balance weights are off.
Aluminium also appears in mixed assemblies: radiators with copper tubing, cables with an aluminium conductor, and utensils with steel handles. We separate these at the yard and pay by component, which is why a mixed load takes longer to grade but returns more than selling it as one lump.
