Aluminium Scrap – Clean / Mixed / Light Gauge

Description

1. Product Overview

This offering comprises high-recovery Aluminium Scrap in Clean, Mixed, and Light Gauge categories, sourced from post-industrial and post-consumer streams with stringent contamination controls. It is primarily used as secondary raw material for remelting into wrought alloys, casting alloys, and deoxidation agents in steelmaking. The key value proposition is a cost-effective alternative to primary aluminium, delivering up to 95% energy savings per ton while maintaining consistent melt yield. Strategically, this product enables buyers to secure circular economy supply chains, mitigate primary price volatility, and meet Scope 3 decarbonization targets.

2. Key Specifications & Technical Characteristics

• Material Composition: Predominantly aluminium (min 88–92% metal content depending on grade); Clean: ≥94% metal; Mixed: 88–92% metal; Light Gauge: 85–90% metal

• Purity / Grade:

  • Clean: 6063, 1050, or 1100 series equivalent – low iron/silicon impurities

  • Mixed: Blend of common alloys (1xxx–6xxx series), max 3% Fe, 2% Cu

  • Light Gauge: Thin-walled profiles, max 5% organic (foils, closures, thin sheet)

• Physical Form: Shredded, briquetted, or loose; particle size: 20–200 mm (clean/mixed) / 5–50 mm (light gauge); bulk density: 0.4–0.8 t/m³

• Color / Appearance: Metallic silver-gray with minimal visible corrosion; light gauge may show minor oxidation

• Packaging Options: 1.2–1.5 MT jumbo polywoven bags (moisture-resistant), 20–25 MT loose in open-top containers, or compacted bales (30–40 kg each)

• Shelf Life: Indefinite when stored indoors or under tarp – no chemical degradation; moisture exposure only affects weight (no quality loss after remelting)

3. Core Industrial Applications

• Secondary Aluminium Smelters & Refiners: Used as feedstock for producing ADC12, A380, or EN AB-46000 alloys. Why better: Uniform melt recovery (tested via TGRS method) reduces furnace yield uncertainty by 40% vs. generic mixed scrap.

• Steel Deoxidation (Ladle Metallurgy): Clean grade charged into ladle furnaces to remove dissolved oxygen. Advantage: Low silica content prevents refractory attack; rapid melting due to high surface-area-to-mass ratio.

• Die Casting Foundries: Mixed grade as blend stock to adjust silicon/iron levels. Cost advantage: 25–35% lower price per ton of contained metal vs. primary ingot, with identical final properties after remelting.

• Master Alloy Production: Light gauge used for aluminum-iron or aluminum-silicon master alloys due to faster dissolution kinetics than heavy scrap.

4. Competitive Advantages

• Quality Consistency: Every lot sampled and analyzed via OES (Optical Emission Spectrometry); certificate of analysis (CoA) provided with each shipment. Inter-lot variability <2% in metal yield.

• Supply Reliability: Minimum 5,000 MT monthly output from integrated collection, sorting, and shredding facilities; 12–15 container loads per week from multiple origin ports (EU, North America, UAE).

• Logistics Capability: Pre-weighed and container-stuffed at source; 20’ and 40’ HC containers with moisture-sealed liners available; dispatch within 10 days of LC confirmation.

• Price Competitiveness: Pricing formula based on LME primary Al minus fixed scrap discount (e.g., LME + premium for logistics). No hidden surcharges for packaging or sampling.

• Sustainability & Compliance: ISRI specification-compliant; EU BIR certified; documented low residual hazardous substances (<0.01% PCBs, Pb, Cd). Enables buyers to claim recycled content for green certifications (e.g., BREEAM, LEED v4).

• Technical Support: Pre-shipment melt yield test (TCLP alternative) upon request; in-person or remote furnace charge optimization consultation.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (bulk, one full 20’ container equivalent)

• Loading Capacity:

  • 20’ standard container: 20–22 MT (baled or bagged) / 18–20 MT (loose light gauge)

  • 40’ high-cube container: 24–26 MT (due to weight limit, not volume) – suitable for bagged clean/mixed only

• Incoterms Offered: FOB loading port, CIF major industrial ports (Rotterdam, Busan, Jebel Ali, Houston), EXW storage yard

• Payment Terms: LC at sight or 30% advance / 70% against BL copy for verified buyers

• Lead Time: 15 days from order confirmation to vessel departure
