China aluminium scrap/aluminum scrap 6063

Buyers must prioritize the purity level, which should ideally be 99% to 99.7% aluminum content. Ensure the scrap is free from excessive oil, grease, and non-metallic attachments like plastic or rubber. For 6063 grade specifically, the Magnesium (Mg) and Silicon (Si) ratios must align with international alloy standards to ensure the recycled material maintains its extrusion properties and structural integrity.

Request a Chemical Composition Analysis (Spectroscopy report) from the supplier for each batch. It is highly recommended to hire a third-party inspection agency (such as SGS or BV) to perform a Pre-Shipment Inspection (PSI). This inspection should verify the weight, contamination levels, and absence of hazardous materials to prevent receiving 'mill scale' or low-grade waste instead of high-quality 6063 scrap.

Suppliers should adhere to ISRI (Institute of Scrap Recycling Industries) specifications, specifically the code 'Tabor' for clean 6063 extrusions. Additionally, ensure the supplier provides a Certificate of Origin and complies with environmental regulations regarding the export of recyclable waste. For buyers in specific regions, check for AQSIQ registration if shipping to or through China-related channels.

Aluminum 6063 scrap is primarily used in the remelting and extrusion industry. It is the preferred raw material for producing architectural profiles, window frames, door systems, and irrigation pipes. Because of its excellent finishing characteristics and corrosion resistance, it is also widely used in the manufacturing of heat sinks and electrical components.

Always use Secure Payment services provided by reputable B2B platforms like Made-in-China.com, which offer Escrow-based protection. Avoid 100% upfront T/T (Telegraphic Transfer) payments to unknown suppliers. Instead, negotiate a 30% deposit and 70% balance against the Bill of Lading (B/L) after a successful third-party inspection report is issued.

The most common risk is weight discrepancy. Ensure the contract specifies that the final weight is determined by a certified weighbridge at the port of loading. Be aware of International Trade Policies regarding 'Green Fence' or 'National Sword' initiatives which strictly regulate the impurity percentage (usually must be <0.5% to 1%) allowed for imported scrap metal.

Pricing for aluminum scrap is usually tied to the LME (London Metal Exchange) spot price. Negotiate based on a percentage of the LME price (e.g., 90% of LME) rather than a fixed USD rate to account for market volatility. Mention your long-term procurement volume to secure a lower 'spread' or discount on the processing fee.

Focus on Audited Suppliers on Made-in-China.com who have a proven track record of exporting to your region. Look for suppliers with ISO 14001 (Environmental Management) and ISO 9001 (Quality Management) certifications. Review their transaction history and buyer feedback to ensure they have the capacity to handle large-scale industrial shipments.
