Lead Ingots (Battery / Shielding)

Description

1. Product Overview
Our Lead Ingots, precision-engineered for battery manufacturing and radiation shielding applications, represent the industry benchmark for density, purity, and electrochemical consistency. These 99.97%+ pure lead ingots serve as the critical raw material for energy storage systems (lead-acid batteries) and nuclear/medical shielding infrastructure. In a market where contaminant levels directly impact cycle life and safety margins, sourcing verified, high-purity lead is a strategic lever for operational reliability and regulatory compliance.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Pb ≥ 99.97%; Impurities strictly controlled (Sb, As, Sn, Cu, Fe, Ag, Bi each < 0.005%)

• Purity Grade: Battery-grade / Shielding-grade (meets ASTM B29-19 / EN 12659 standards)

• Physical Form: Rectangular ingots with stacking ridges

• Dimensions: Approx. 450mm x 95mm x 85mm (customizable upon volume commitment)

• Density: 11.34 g/cm³ @ 20°C

• Weight per Ingot: 22–25 kg (± 1%)

• Packaging Options: Steel-strapped pallets (1.2–1.5 MT per pallet) | Heat-shrink wrapped | Export seaworthy wooden crates

• Shelf Life: Indefinite under dry storage (non-hygroscopic, no degradation)

3. Core Industrial Applications

• Lead-Acid Battery Manufacturing (80% of demand): Used for positive/negative grids, lugs, and oxide production. Our ingots reduce gassing and self-discharge due to ultra-low antimony and silver content – directly extending battery cycle life by 15–20% versus standard secondary lead.

• Radiation Shielding (Medical & Nuclear): Fabricated into protective liners for X-ray rooms, CT scanners, nuclear waste transport containers, and reactor shielding. The high density and absence of micro-voids ensure predictable linear attenuation coefficients – a non-negotiable safety parameter.

• Soundproofing & Vibration Damping: Ideal for architectural acoustic barriers in recording studios or industrial machinery enclosures, outperforming polymer alternatives in mass-loaded vinyl applications.

Why superior: Lower bismuth content (<50 ppm) prevents anode corrosion in batteries. For shielding, our homogeneity eliminates “hot spots” – unlike recycled lead with embedded impurities.

4. Competitive Advantages

• Quality Consistency: Every batch is spectrometer-tested with a signed Certificate of Analysis (CoA). Inter-batch variation below 0.02% – critical for automated battery paste mixing lines.

• Supply Reliability: Vertically integrated sourcing (primary smelting + controlled secondary refining) ensures 52-week year-round availability. 98% on-time-in-full (OTIF) track record to Asia, Europe, and Americas.

• Logistics Capability: In-house container stuffing + full customs documentation (HS code 7801.10). Pre-shipment photos and weight certificates provided.

• Price Competitiveness: Direct mill pricing with monthly LME-linked formula – no trader markup. Volume rebates from 500 MT/quarter.

• Environmental & Technical Support: ISO 14001-certified refining. Free technical datasheet on alloying (e.g., calcium-lead or tin-lead ratios). Upon request, metallurgical advisory for die-casting parameters.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20 METRIC TONS (approx. 800–900 ingots)

• Loading Capacity (per standard 20’ container): 25 MT (tight-stuffed palletized)
  For 40’ HC container: up to 26–28 MT, subject to weight restrictions per carrier

• Lead Time: 14–21 days ex-warehouse (Rotterdam / Houston / Shanghai hubs)

• Incoterms: FOB, CIF, CFR, EXW available
