Chemical Composition
Elemental breakdown by percentage weight.
Standard composition limits
Values represent maximum allowed percentage unless otherwise noted.
Physical Properties
Material form, density, and contamination specifications.
End-of-life electric motors; industrial/automotive equipment decommissioning; MODERATE precious metal content (12-30% copper primary; 50-70% steel secondary); LOW hazmat complexity (no special electrolyte/oil; straightforward mechanical); SUBSTANTIAL supplier diversity (312 suppliers; motor ubiquity in industrial equipment); MEDIUM value commodity; copper recovery valuable; steel significant; minimal hazmat concern; motor recycling mature infrastructure; straightforward processing; environmental compliance standard
Acceptable Inclusions
