aluminum scrap

Selecting the correct grade is critical for smelting efficiency. Buyers should distinguish between Clean Aluminum Wire (Talon/Taste), Mixed Aluminum Castings (Tense), and Aluminum Extrusions (6063/6061). Ensure the scrap is categorized by its alloy series and purity levels, as high-purity scrap (99%+) significantly reduces energy consumption during the recycling process. Always request a chemical composition analysis (Spectrometer report) to verify the presence of iron, silicon, and magnesium.

International trade of scrap metal is strictly regulated. Ensure the product complies with ISRI (Institute of Scrap Recycling Industries) specifications, which define standard grades for non-ferrous scrap. For cross-border trade, the supplier must provide a Pre-shipment Inspection Certificate (PSIC) and adhere to ISO 9001 for quality management. Additionally, verify that the scrap is free from radioactive materials, medical waste, and excessive moisture or oil, which can pose safety risks during melting.

The value of scrap is determined by its recovery rate (yield). Buyers should conduct a melt test on samples to calculate the percentage of usable metal versus dross/slag. Factor in the LME (London Metal Exchange) aluminum price index as a benchmark for pricing. To optimize costs, prioritize baled or densified scrap to maximize container loading capacity, thereby reducing the freight cost per ton.

Confirm the physical dimensions of the scrap (e.g., shredded, briquetted, or loose) to ensure compatibility with your furnace charging system. For specialized applications like automotive parts, ensure the magnesium and copper content is within the allowable limits of your final alloy recipe. If purchasing UBC (Used Beverage Cans), verify if they are decoated to prevent excessive oxidation during the melting process.

The primary risks include quality substitution (receiving lower-grade scrap than sampled) and weight discrepancies. To mitigate these, use third-party inspection services like SGS or CCIC at the loading port. Be wary of prices significantly below the LME market average, as this often indicates potential fraud or contaminated material.

Many countries have strict import quotas and environmental bans on solid waste. Ensure the supplier has a valid Export License and that you possess the necessary Import Permits for your specific country. Documentation must clearly state the scrap is a secondary raw material rather than 'waste' to avoid customs seizures or heavy fines.

For new suppliers, avoid 100% advance payments. Utilize Irrevocable Letters of Credit (L/C at sight) or Trade Assurance services provided by reputable platforms like Made-in-China.com. This ensures that payment is only released upon the presentation of valid Bill of Lading (B/L) and inspection certificates.

Aluminum scrap is typically shipped in 20ft or 40ft containers. Ensure the scrap is securely loaded and lashed to prevent shifting during transit, which can damage the container walls. Negotiate Incoterms like CIF or CFR to simplify logistics, but ensure the marine insurance covers 'all risks' including contamination or loss at sea.
