Aluminum Wheels
Cast aluminum automotive wheels and truck wheels
Certification Requirements
Required certifications, standards compliance, and verification protocols.
Wheel collection from dismantlers, assessment, brake dust evaluation, structural verification, quality control

Rejection Criteria
Conditions and thresholds that trigger immediate rejection or downgrading.
Steel wheel detected OR non-aluminum base
FULL REJECTION or immediate segregation
- Critical: Wrong Material
- Aluminum Specification Violated
Visual inspection + magnetic test
CRITICAL - MATERIAL TYPE VIOLATION
- Automatic Rejection
- Material Segregated As Steel/Ferrous Scrap
Tire rubber >0.5% OR visible rubber saturation
- Immediate Full Rejection
- Hazmat Protocol If Required
- Hazmat: Rubber Volatiles Toxic
- Worker/Environmental Safety Critical Concern
Visual inspection + thermal analysis
CRITICAL - HAZMAT/SAFETY
- Automatic Rejection
- Hazmat Disposal Protocols Apply
- Potential Regulatory Notification
Al <88%
Full rejection or reclassification
Material purity below wheel specification
XRF spectrometry
CRITICAL - SPECIFICATION VIOLATION
Full lot rejection or downgrading to lower grade
Mg <1% OR alloy NOT confirmed as 5000-series
Full rejection or reclassification to generic casting
- Material Not Automotive Wheel Alloy
- 5000-Series Specification Violated
XRF spectrometry alloy analysis
CRITICAL - ALLOY SPECIFICATION
Reclassification to lower-tier generic casting grade
Major cracks, warping, or casting defects evident
Full rejection or substantial reclassification to scrap grade
- Structural Integrity Compromised
- Smelting Hazard
- Material Loss/Recovery Issue
Visual inspection + magnetic particle inspection
CRITICAL - STRUCTURAL
- Rejection Or -£300-500/Mt Penalty
- Reclassification To Scrap Aluminum
Brake dust >2% OR heavy accumulation preventing inspection
Full rejection or cleaning required at supplier cost
