Aluminium

Primary aluminium ingots are remelt products defined by aluminium grade and controlled elemental limits. Procurement should distinguish exchange or standards references from the producer's actual ingot chemistry, dimensions, bundle mass and brand eligibility.

Aluminium alloy ingots are selected by alloy designation and a complete chemistry window, not by aluminium content alone. The enquiry should state casting process, application, restricted elements, ingot size and whether recycled-content documentation is required.

Aluminium extrusion billets are cylindrical feedstock defined by alloy, diameter, length, homogenization condition and surface quality. Extrusion performance depends on verified chemistry and process evidence for the quoted billet source.

Aluminium scrap is procured by alloy family, physical form, cleanliness and recoverable-metal basis. Painted, coated, oily, mixed or attached materials require separate classification and may trigger waste-shipment and pre-treatment controls.
