Aluminium scrap 6063 manufacturers

Buyers must ensure the scrap meets the ISRI (Institute of Scrap Recycling Industries) code for 'Tense' or 'Tabor' depending on the form, but specifically for 6063, it should be clean aluminum extrusions. The aluminum content should ideally be 98% to 99%, with magnesium and silicon levels consistent with the 6063 alloy series. It is critical to verify that the scrap is free of zinc, iron (less than 0.5%), oil, grease, and non-metallic attachments like plastic or rubber thermal breaks.

Request a SGS or CCIC third-party inspection report which includes a Spectrometer Analysis to confirm the chemical composition. For bulk orders, ask the supplier for a loading video and photos of the material being weighed. It is highly recommended to check for moisture content and oxidation levels, as excessive 'white rust' or corrosion can significantly reduce the melting yield and increase slag during processing.

Aluminium 6063 scrap is primarily used for remelting and extrusion. It is a favorite in the construction industry for producing window frames, door frames, and roofing, as well as in the automotive sector for trim and structural components. Because of its excellent finishing characteristics and high corrosion resistance, it is also widely used in the manufacturing of heat sinks and irrigation pipes.

Suppliers must provide a Certificate of Origin and a Mill Test Certificate (MTC) if available. For shipments to specific regions like China, a GB/T 13586 standard compliance is necessary. Ensure the supplier adheres to ISO 9001 for quality management and ISO 14001 for environmental management, as scrap metal trade is heavily regulated regarding hazardous waste contamination.

The biggest risk is material substitution or contamination (e.g., hiding heavy iron or stones inside the scrap bales). To mitigate this, use Escrow payment services or Letters of Credit (L/C) that only release funds upon the presentation of a clean inspection report from a reputable agency like SGS. Avoid 100% upfront T/T payments to unknown suppliers.

Pricing is usually pegged to the LME (London Metal Exchange) aluminum price. Negotiate based on a percentage of the LME spot price (e.g., 90% of LME). Be wary of suppliers offering prices significantly below the market average, as this is a major red flag for potential fraud or extremely low-quality material.

Ensure the scrap is packed in tightly pressed bales or big bags to maximize container space and prevent shifting during transit. For sea freight, clarify the Incoterms; CIF (Cost, Insurance, and Freight) is common, but FOB (Free On Board) gives the buyer more control over the shipping timeline and costs. Always confirm the free time at the destination port (demurrage) to avoid high fees during customs clearance.

Utilize professional B2B platforms like Made-in-China.com, focusing on Audited Suppliers who have undergone on-site factory inspections. Look for suppliers with a long history of exports and positive buyer reviews specifically regarding metal commodities.
