Aluminum Wire
Aluminum electrical wire and cable, pure or mixed alloys
Certification Requirements
Required certifications, standards compliance, and verification protocols.
Wire collection, assessment, hazmat screening, stripping coordination, quality verification
Supplier must maintain active ISO 9001 certification throughout contract term
- Aluminum content: 90-99.5% confirmed (electrical wire spec)
- Copper content: ≤3.0% documented (cable shielding acceptable)
- Iron content: <1.0% confirmed (ferrous contamination control)
- Conductor type: aluminum (NOT copper) verified
- Insulation material: type identified (PVC, PE, rubber, or other)
- Insulation residue: <5% expected post-stripping documented
- Asbestos presence: NEGATIVE (critical for pre-1980 materials)
- PCB (polychlorinated biphenyls): NEGATIVE confirmed
- Lead paint: assessment completed (if pre-1978 sheath suspected)
- Chlorine content: assessed if PVC-based insulation
- Wire gauge/type: identified (utility standard documented)
- Hazmat assessment: worker safety protocols specified
- VOC/solvent presence: documented (processing concern)
MUST state:
- Conductor material verified as ALUMINUM (not copper)
- weight/conductivity characteristics consistent with aluminum electrical grade
- copper wire contamination ABSENT
MUST state:
- Asbestos screening: NEGATIVE
- PCB assessment: NEGATIVE
- Chlorine hazard (if PVC): assessed and [acceptable/requires hazmat protocol]
- Worker safety: [approved for standard processing OR requires specialized protocols]

£1-2 million (aluminum commodity + hazmat/VOC processing risk)
Rejection Criteria
Conditions and thresholds that trigger immediate rejection or downgrading.
Copper conductor primary (not aluminum); Cu >3.0% if primary conductor
IMMEDIATE FULL REJECTION or complete segregation required
- Critical: Copper Wire ≠ Aluminum Wire (Fundamentally Different Commodities)

Visual inspection + weight test + XRF spectrometry
CRITICAL - MATERIAL TYPE VIOLATION (ABSOLUTE)
- Automatic Rejection
- Material Segregated As Copper Scrap (Not Aluminum)
Asbestos detected in insulation OR pre-1980 cable with asbestos suspected
- Immediate Full Rejection
- Hazmat Protocol Mandatory
- Critical Health Hazard
- Occupational Exposure Risk
- Regulatory Violation
- Worker Protection Violation
Visual age assessment + expert determination + optional lab analysis
CRITICAL - HEALTH/SAFETY HAZARD (ABSOLUTE)
- Entire Lot Rejected
- Hazmat Disposal Protocols Apply
- Regulatory Authority Notification Possible
Polychlorinated biphenyls detected in cable sheathing
