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.

Post-consumer zinc die-casting scrap; automotive hardware, door hardware, locks, hinges, chassis components, fittings; industrial hardware and equipment components; end-of-life vehicle recycling source; hardware retailer/distributor scrap; used condition with age/oxidation; established zinc recycling stream

Acceptable Inclusions

Zinc 80-98% (die-cast specification)
Copper <10% (die-cast alloy critical)
Lead <4% (legacy castings acceptable; hazmat trace)
Aluminum <4% (alloy component)
Tin <4% (hardening element)
Magnesium <3% (alloy component)
Iron <2% (minimal ferrous contamination)
Cadmium <0.01% (hazmat trace)
Surface oxidation/patina expected

Prohibited Materials

Zinc <80% (insufficient purity)
Copper >10% (exceeds die-cast composition)
Lead >4% (excessive hazmat)
Cadmium >0.01% (HAZMAT exceeds)
Ferrous or stainless contamination (>2%)
Unknown alloy composition
Heavy corrosion damage (>50% surface)
Mercury or radioactive contamination

Quality Assurance

Testing protocols, sampling methods, and acceptance criteria.

Sampling Protocol

frequencyStratified random sampling by fragment type/size; cadmium screening; ultra-pure verification mandatory

maximumQuantity80-100 samples per shipment

minimumQuantity0.5-1 tonne or 30-50 fragment samples

percentage5-8% of lot

stratificationSample across different manufacturing trim types; geometry variation; cadmium risk assessment comprehensive

Required Test Methods

Visual Inspection & New Production Zinc Confirmation

CRITICAL

Method 1

Purpose

confirm new production zinc diecast (not used material)
verify virgin manufacturing-source condition
assess oxidation minimal
verify primary processing readiness

Acceptance Criteria

New zinc die-cast scrap unmistakable characteristic
factory-fresh condition
minimal oxidation patina
no service wear evident
primary processing ready

Procedure

100% sample visual inspection (purity priority)
verify new/clean zinc color
confirm factory manufacturing trim form
assess condition excellent
verify NO service wear evidence

Cadmium Ultra-Sensitive Screening

CRITICAL

Method 2

Purpose

detect ANY cadmium >0.005% ppb-level (occupational health hazard extreme
worker toxicity concern)

Acceptance Criteria

Cadmium absolutely NOT detected OR quantified <0.005% ppb level
health hazard controlled
safety threshold met

Lead Content Verification

Method 3

Purpose

Verify lead <0.5% (modern lead-free specification
occupational hazard control)

Acceptance Criteria

Lead <0.5%
modern lead-free formulation confirmed
occupational health standard met

Iron Contamination Assessment

CRITICAL

Method 4

Purpose

verify iron <0.2% (primary processing ultra-strict specification
smelter contamination prevention)

Acceptance Criteria

Iron <0.2%
primary processing specification met
smelter protocol compatible

New Production Condition Verification

Method 5

Purpose

Verify new production condition (not used/service material)
confirm factory-fresh manufacturing scrap

Acceptance Criteria

New production authenticity confirmed
factory-fresh condition evident
no service wear

Zinc Purity Assessment

Method 6

Purpose

Verify zinc 95-99.5% (primary processing ultra-pure specification
direct smelter feedstock)

Acceptance Criteria

Zinc 95-99.5%
ultra-pure specification confirmed
primary processing feedstock approved

Comprehensive ICP-AES Analysis

CRITICAL

Method 7

Purpose

COMPREHENSIVE ULTRA-SENSITIVE verification: Zn 95-99.5%
