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.

Specialty high-lead bronze scrap; copper-tin-lead alloy for bearing and bushing applications; controlled lead content for functional and safety purposes; specialized foundry feedstock; supply-limited specialty metal

Acceptable Inclusions
  • Light surface oxidation and patina
  • Machining oil residue (<1%)
  • Light corrosion from age/use
  • Lead 5-15% (high-lead bronze specification)
  • Tin 3-10% (bronze component)
  • Zinc <3% (minor contamination)
  • Iron <1.5% (ferrous tolerance)
Prohibited Materials
  • Copper content <75% (must be high-lead bronze minimum)
  • Tin content <3% (must be bronze range)
  • Lead <5% (insufficient lead for high-lead grade)
  • Lead >15% (exceeds foundry safety tolerance; processing hazard)
  • Arsenic >0.5% (HAZMAT; occupational exposure risk)
  • Stainless steel or aluminum contamination
  • Heavy oil/coolant saturation (>2%)
  • Unknown bronze type (composition uncertain)
  • PCB or electronic components
  • Radioactive materials

Required Test Methods

Visual Inspection & Bronze Confirmation

MANDATORYABSOLUTE
Method 1
Purpose
  • confirm high-lead bearing bronze (not brass, not copper, not low-lead)
  • assess contamination
  • detect foreign material hazards
Acceptance Criteria
  • Bronze coloration characteristic (darker/redder than brass)
  • no visible ferrous/aluminum/stainless contamination
  • acceptable condition
Procedure
  • 100% visual inspection
  • confirm bronze appearance
  • identify bearing bronze scrap types
  • flag non-bronze material

Magnetic Test

CRITICAL
Method 2
Purpose
  • exclude ferrous contamination
