Published by Metal Island · March 2026
Aluminium 6063 extrusion scrap is one of the most valuable and widely traded grades in the industrial metal recycling market. Known as the "architectural alloy," 6063 scrap comes primarily from window frames, door profiles, shop fittings, and irrigation tubing. For manufacturing units in Bangalore and across India, understanding how to source, verify, and price this material is critical for cost-effective operations and sustainable production.
What is Aluminium 6063 Extrusion Scrap?
Aluminium 6063 is a magnesium-silicon alloy belonging to the 6xxx series, specifically designed for extrusion processes. It offers medium strength, excellent corrosion resistance, superior surface finish, and outstanding anodizing characteristics. These properties make it the most common alloy used for architectural and decorative applications.
Key Characteristics of 6063 Alloy:
- Exceptional extrudability and formability
- Excellent surface finish suitable for anodizing
- High corrosion resistance in architectural environments
- Good weldability using standard methods
- Lightweight with density of 2.702 g/cm³
- Melting point: 660.37°C

How to Verify Quality: Metal Island's Testing Process
Quality verification is critical when sourcing aluminium 6063 extrusion scrap. At Metal Island, we employ a comprehensive multi-stage testing protocol to ensure material authenticity and compliance.
Stage 1: Visual Inspection & Physical Verification
- Profile Identification: Verify source (window frames, door profiles, irrigation tubes)
- Contamination Check: Ensure absence of screws, plastic, rubber, iron attachments
- Surface Condition: Assess for paint, coatings, anodizing layers
- Physical Form: Confirm proper cutting, cleaning, and densification (for baled scrap)
- Color Verification: Silver-white color typical of 6063 alloy
Stage 2: Spectrometric Analysis
We use advanced X-Ray Fluorescence (XRF) or Optical Emission Spectrometry (OES) to verify chemical composition:
- Alloy Confirmation: Distinguish 6063 from similar grades (6061, 6005, cast aluminium)
- Purity Assessment: Measure aluminium content (typically 95-99%)
- Contaminant Detection: Identify excessive iron, copper, or other metallic impurities
- Certification: Generate spectrographic analysis report for documentation
Stage 3: Mechanical Testing (When Required)
- Hardness Testing: Brinell or Rockwell tests to verify temper condition
- Tensile Testing: Confirm yield and ultimate tensile strength (per ISO 6892)
- Non-Destructive Testing: Ultrasonic testing for internal defects in critical applications
Stage 4: Documentation & Traceability
Metal Island provides comprehensive documentation for every batch:
- Mill Test Certificate (MTC) with chemical composition analysis
- Batch identification and source traceability
- Weight verification and packaging details
- ESG compliance and environmental certifications
- GST documentation and regulatory compliance
Common Quality Issues & Red Flags
Watch Out For:
- Mixed Alloy Scrap: 6063 contaminated with 6061, cast aluminium, or other grades
- Excessive Attachments: Screws, plastic inserts, glass, rubber seals not properly removed
- Heavy Coating/Paint: Reduces actual aluminium recovery percentage
- Moisture Content: Can affect weight and processing efficiency
- Unrealistic Pricing: Prices significantly below market rates often indicate quality issues
- No Testing Reports: Absence of spectrometric analysis or mill certificates

Frequently Asked Questions
What is the difference between 6063 and 6061 aluminium scrap?
While both are 6xxx series alloys, 6063 has lower magnesium content and is optimized for extrusion with excellent surface finish and anodizing properties. 6061 contains more magnesium and silicon, offering higher strength but reduced extrudability. Scrap pricing typically differs by USD 50-100 per tonne, with 6061 commanding premium rates due to superior mechanical properties.
How can I verify if the scrap is genuine 6063 and not mixed alloy?
The only reliable method is spectrometric testing using XRF or OES analyzers, which determine exact chemical composition within minutes. Visual inspection alone cannot distinguish 6063 from similar alloys. Reputable extrusion scrap buyers like Metal Island provide certified test reports with every batch. Always insist on independent verification before bulk procurement.
What is the current price trend for aluminium 6063 scrap in Bangalore?
As of March 2026, Bangalore market rates are INR 220,000-225,000 per tonne for clean domestic 6063 extrusion scrap, showing a premium over Delhi NCR (INR 185,000-190,000) due to higher local demand from South India's manufacturing clusters. Import prices stand at USD 2,865-2,950 per tonne CFR basis. Prices are expected to remain firm due to tight domestic supply and strong demand from automotive and construction sectors.
What should be the acceptable contamination level in 6063 scrap?
Industry-standard clean 6063 extrusion scrap should have less than 2% total contamination (plastic, rubber, iron attachments, paint). Scrap with 2-5% contamination is considered "commercial grade" and priced 5-8% lower. Material with over 5% contamination significantly impacts melting efficiency and should be rejected or heavily discounted. Always specify maximum contamination thresholds in procurement contracts.
Which industries in Bangalore are the largest consumers of 6063 scrap?
Bangalore's primary consumers include secondary aluminium smelters producing ADC12 alloy ingots for automotive die-casting (40%), re-extrusion units for architectural profiles (25%), aerospace component manufacturers (15%), electronics heat sink producers (12%), and general metal fabricators (8%). The city's strong automotive and aerospace clusters make it a major recycling hub for aluminium recycling in India.
