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.

Premium high-copper brass; 85%+ copper content places material at boundary of brass/copper classification; direct ingot feedstock; supply-constrained commodity

Acceptable Inclusions

Light surface oxidation/patina
Minimal machining oil residue (<0.5%)
Very light dirt or dust
Minor age-related corrosion
Lead <1.0% (strict premium tolerance)
Tin <0.5% (minimal bronze acceptable)
Iron <0.5% (ferrous limit strict)

Prohibited Materials

Copper content <85% (must be red brass minimum)
Zinc content >15% (yellow brass; different grade)
Lead >1.0% (exceeds premium specification)
Stainless steel mixing
Aluminum or major non-ferrous contamination
Heavy machining oil or coolant residue (>1%)
Asbestos insulation or coatings
PCB components attached
Plastic or rubber components
Radioactive materials
Mixed metal uncertainty (composition unclear)
Heavy corrosion/rust (compromises material purity)

Quality Assurance

Required Test Methods

Visual Inspection

Method 1

Purpose

Confirm RED BRASS material (reddish coloration)
detect contamination
verify premium condition

Acceptance Criteria

Distinctive red/reddish appearance evident (copper-rich identity)
NO yellow/golden tones (yellow brass)
NO silver appearance (aluminum)
minimal oxidation
premium material character clear

Procedure

100% visual scan of all samples
confirm red brass coloration vs. other materials
assess oxidation level
identify any visible contamination
compare to reference red brass standards

Red Brass Material Verification

CRITICAL

Method 2

Purpose

confirm COPPER-RICH COMPOSITION (85%+ copper)
distinguish from yellow brass

Acceptance Criteria

Material confirms as red brass high-copper composition
NOT yellow brass (lower copper)
NOT pure copper
distinctive red appearance confirmed

Copper Content Verification

CRITICAL

Method 3

Purpose

verify 85-95% copper specification (defining characteristic)

Acceptance Criteria

Copper 85-95% documented
red brass specification confirmed

Zinc Content Assessment

CRITICAL

Method 4

Purpose

verify zinc 5-15% (distinguishes from pure copper >95%)

Acceptance Criteria

Zinc 5-15% confirmed
red brass balance verified

Lead Screening

CRITICAL

Method 5

Purpose

verify ≤1.0% lead (strict premium specification gate)

Acceptance Criteria

Lead <1.0% confirmed
premium purity specification met

Magnetic Test

Method 6

Purpose

Exclude ferrous/stainless contamination
verify non-magnetic character

Acceptance Criteria

Non-magnetic or very weak magnetism (red brass expected)
NO strong ferrous response

Procedure

Magnet test on samples
red brass should be essentially non-magnetic

Oxidation Level Assessment

Method 7

Purpose

Evaluate oxidation/corrosion development
assess premium material preservation

Acceptance Criteria

Light oxidation/patina acceptable
NO heavy corrosion/pitting
premium condition confirmed

Procedure

Visual oxidation assessment
surface condition evaluation
compare to acceptable oxidation standards

XRF Spectrometry

Method 8

Purpose

COMPREHENSIVE verification of red brass 85-95% Cu + all contamination assessment (Pb, Sn, Fe, Al, Ni)

Acceptance Criteria

Cu 85-95% (RED BRASS CONFIRMED), Zn 5-15%, Pb <1.0% (STRICT), Fe <0.5%, Sn <0.5%, Ni <0.3%, Al <0.2%
