Zinc Scrap

Description

1. Product Overview
Zinc Scrap is a high-purity secondary raw material derived from post-industrial and post-consumer zinc-based products, including die-cast alloys, galvanized steel residues, and zinc sheet trimmings. It serves as a cost-efficient substitute for primary zinc in galvanizing, brass production, and chemical manufacturing. With tightening global zinc supply chains and surging demand for low-carbon feedstocks, this scrap enables buyers to reduce material costs by 15–25% while lowering embodied carbon emissions—making it a strategically critical input for sustainable metallurgical operations.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Zn 92–98%, Fe ≤ 2%, Al ≤ 1%, Pb ≤ 0.5%, Cd ≤ 0.3% (depending on scrap grade)

• Material Types Available:

  • Zinc die-cast scrap (clean)

  • Zinc galvanizing dross (high Zn content)

  • Mixed zinc alloys (Zn–Al, Zn–Cu)

• Physical Characteristics:

  • Form: Shredded, baled, or bulk loose pieces (20–200 mm particle size)

  • Color: Silver-grey with minimal oxidation

  • Density: Approx. 2.5–3.5 g/cm³ (bulk density varies by form)

• Packaging Options:

  • 1 MT jumbo bags

  • Loose in 20’ or 40’ containers (container-lined)

  • Shrink-wrapped pallets for smaller lots

• Shelf Life: Indefinite when stored dry; no degradation risk under standard warehouse conditions

3. Core Industrial Applications

• Galvanizing Industry: Used as a secondary zinc feed in hot-dip galvanizing baths. Outperforms primary zinc in cost-per-unit-mass without compromising coating adhesion or corrosion resistance.

• Brass & Bronze Production: Directly melted into Cu–Zn alloys. Provides faster melt times and lower energy consumption versus primary ingots due to higher surface area.

• Chemical Manufacturing (ZnO, ZnSO₄): Ideal feedstock for producing zinc oxide and zinc sulfate. Allows chemical refiners to lower raw material input cost by up to 20% with identical final product purity after processing.

• Die-Casting Foundries: Recycled internally or externally as remelt alloy. Reduces dross formation compared to virgin zinc when properly sorted.

Commercial advantage: Buyers achieve equivalent metallurgical performance at 10–20% lower procurement cost, with faster melting kinetics and reduced oxidation loss.

4. Competitive Advantages

• Quality Consistency: Every shipment is spectrographically tested; certificates of analysis provided per ISO 9001:2015 standards.

• Supply Reliability: Long-term offtake agreements with industrial dismantlers and galvanizing lines ensure 5,000+ MT monthly availability from multiple origins (Europe, North America, SE Asia).

• Logistics Capability: FCL and LCL shipping worldwide; hazardous-free classification (non-dangerous goods) simplifies customs clearance.

• Price Competitiveness: Priced at LME Zinc primary minus 12–18% discount, fixed or floating index-based contracts available.

• Sustainability Advantage: Using zinc scrap reduces CO₂ emissions by ~75% compared to primary zinc production (source: IZA data). Compliant with EU CBAM and ISO 14044 LCA standards.

• Technical Support: Dedicated metallurgical engineer support for melt recipes, impurity management, and downstream process optimization.

5. Commercial & Supply Information
