Architectural Grade 6063
Extrusion Scrap.
Premium 6000-Series Recovery
HUTKA SA aggregates and processes high-purity 6063 aluminum extrusion scrap, primarily sourced from architectural tear-downs, door and window manufacturing offcuts, and structural profiles.
Available in both clean, mill-finish profiles (ISRI “TATA”) and painted/anodized mixtures (ISRI “TUTU”), our extrusion scrap provides secondary smelters with an exceptionally reliable magnesium-silicon (Mg-Si) alloy base. Through rigorous mechanical sorting, we ensure all materials are strictly free of iron attachments, thermal breaks, and plastic weather stripping, maximizing billet casting efficiency.
Alloy Composition & Tolerances
Our extrusion scrap consists exclusively of 6000-series alloys (predominantly 6063). We enforce strict contractual thresholds on iron, zinc, and non-metallic contamination to protect the structural integrity of the final cast billets.
| Base Composition & Yield (6063) | |
|---|---|
| Alloy Series | 6000 Series (6063/6061) |
| Silicon (Si) | 0.20% — 0.60% |
| Magnesium (Mg) | 0.45% — 0.90% |
| Expected Recovery Yield | 95.0% – 98.0% (TATA) |
| Radioactivity | None Detected (0.00 Bq/g) |
| Strict Contamination Limits (%) | |
|---|---|
| Iron (Fe) | 0.35% Max (Tightly Controlled) |
| Zinc (Zn) Attachments | Strictly Excluded |
| Thermal Break Plastics | Strictly Excluded |
| Dirt / Non-Metallics | 1.0% Max |
| Moisture | 1.0% Max |
Densification & Shearing
Architectural extrusions are inherently long and bulky, making raw transport uneconomical. HUTKA SA utilizes heavy-duty alligator shears to cut long profiles into manageable lengths before feeding them into hydraulic baling presses.
The resulting high-density briquettes and bales drastically lower ocean freight costs and ensure optimal melting efficiency when introduced into our partners’ reverberatory or induction furnaces.
Decarbonizing Construction Materials
Aluminum extrusions are heavily utilized in global infrastructure and green building projects. By recovering and processing end-of-life window frames and architectural scrap, HUTKA SA closes the loop on construction waste. Recycling 6063 aluminum consumes only 5% of the energy required to produce primary aluminum, directly allowing our foundry partners to offer “Low-Carbon” or “Green” billets to modern developers.
Processing & Export Protocols
Independent surveyors from BQCIS visually inspect the scrap, conduct magnet tests for ferrous attachments, and verify the total exclusion of thermal break plastics before baling.
Hydraulic Baling
Extrusions are hydraulically compressed into dense, interlocking bales (approx 500kg – 1,000kg). They are banded with heavy-duty aluminum wire or plastic strapping to prevent expansion.
Industrial Palletization
Bales can be stacked and shrink-wrapped onto standard ISPM-15 certified wooden pallets, facilitating rapid, safe forklift extraction upon arrival at the destination foundry.
FCL Containerization
Pallets and bales are forklift-loaded into standard 40′ High Cube FCL containers, maximizing payload efficiency at ~22 to 25 Metric Tons per container. Bolt seals are applied immediately.
Standard Commercial Documentation
Every shipment is cleared for international customs with a comprehensive, fully compliant document packet dispatched via express courier to the buyer’s bank or office.
