China aluminium scrap/aluminum scrap 6063 manufacturers

Buyers must prioritize the purity level, which should ideally be 99% or higher for high-quality 6063 scrap. Ensure the material is free of excessive oil, grease, and non-metallic attachments like plastic or rubber. The scrap should be categorized as 'Tense' (cast) or 'Taint/Tabor' (clean sheet), but specifically for 6063, it is often sourced as extrusion scrap. Verify that the iron (Fe) content is below 0.35% and magnesium (Mg) is within the 0.45-0.9% range to ensure it meets the chemical composition standards for remelting.

Sourcing scrap metal requires strict adherence to AQSIQ (General Administration of Quality Supervision, Inspection and Quarantine) standards if exporting from or importing to specific regions. Ensure the supplier provides a Certificate of Analysis (COA) and follows ISRI (Institute of Scrap Recycling Industries) specifications. For cross-border trade, the scrap must be non-hazardous and compliant with the Basel Convention regulations regarding the transboundary movement of recyclable materials.

Aluminium 6063 scrap is highly valued for its excellent extrudability and corrosion resistance. It is primarily used in the construction industry for window frames, door frames, and roofing. It is also a critical raw material for automotive components, electrical conduits, and architectural structures. Because it is easily anodized, it is the preferred choice for products requiring a high-quality surface finish.

Pricing is typically indexed to the LME (London Metal Exchange) or SMM (Shanghai Metals Market) spot prices. Buyers should negotiate based on a percentage of the LME price (e.g., 90-95% of LME) depending on the purity and volume. Always calculate the recovery rate (yield); high-quality 6063 scrap should yield 90% to 96% usable metal after smelting. Be wary of prices significantly below market averages, as this often indicates contamination or fraudulent grading.

The biggest risk is quality substitution, where the delivered scrap contains heavy metals or waste instead of 6063 aluminium. To mitigate this, always hire a third-party inspection agency like SGS or CCIC to perform a pre-shipment inspection (PSI) for weight and quality. Use Secure Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment and inspection.

Focus on long-term partnership potential rather than a one-off transaction to secure better pricing. Request detailed photos and videos of the actual stock in the warehouse, not just stock images. Negotiate for incoterms like CIF (Cost, Insurance, and Freight) to simplify logistics, but ensure the Bill of Lading (B/L) is verified through official channels before final payment.

Aluminium scrap is usually shipped in 20ft containers to maximize weight capacity. Ensure the scrap is properly baled or bundled to prevent shifting during transit, which can damage the container. Verify the loading weight limits of the destination port to avoid heavy-weight surcharges. For documentation, ensure the Packing List, Commercial Invoice, and Certificate of Origin are meticulously prepared to avoid customs delays or seizures.
