Lead Block[2]
Overview
Lead Block is a solid form of lead, typically cast into rectangular or cylindrical shapes for industrial use. It is valued for its exceptional density, corrosion resistance, and malleability. Historically used in construction and plumbing, modern applications focus on radiation shielding, battery manufacturing, and precision weights. Lead's low melting point (327.5°C) makes it easily recyclable, contributing to its sustainability in industrial cycles. B2B buyers typically procure lead blocks in standardized sizes ranging from 5kg to 1000kg, with purity levels between 99.5% to 99.99% depending on application requirements.
Physical and Chemical Properties
Lead blocks exhibit a bluish-gray color when freshly cut, oxidizing to a dull gray over time. With a density of 11.34 g/cm³, it is one of the densest common metals, surpassed only by mercury and gold. This property makes it ideal for radiation shielding in medical and nuclear applications. Chemically, lead resists corrosion from sulfuric acid and many other chemicals, though it reacts with nitric acid. Its face-centered cubic crystal structure contributes to exceptional malleability, allowing it to be rolled into thin sheets without cracking. The metal becomes superconductive at temperatures below 7.2K.
Main Applications
Approximately 80% of lead block production serves battery manufacturing, particularly for lead-acid batteries in vehicles and backup power systems. In construction, lead blocks are used as vibration dampers in skyscrapers and as flashing material for waterproofing. The healthcare sector utilizes lead blocks for radiation shielding in X-ray rooms and nuclear medicine facilities. Other applications include fishing sinkers, sailboat keels, and bullet manufacturing. Emerging uses include lead bricks for particle physics research and as counterweights in industrial machinery.
Safety and Storage
Lead blocks require careful handling due to toxicity risks. OSHA mandates airborne exposure limits below 50 µg/m³ (8-hour TWA). Proper storage involves dry conditions with secondary containment to prevent lead dust accumulation. Workers should use NIOSH-approved respirators when cutting or machining lead blocks. For long-term storage, coat lead blocks with a thin layer of oil or wax to prevent oxidation. Never store near food products or in areas with high foot traffic. Spill containment measures should include plastic-lined containers and HEPA vacuum cleaners for cleanup.
B2B Procurement Guide
When sourcing lead blocks, prioritize suppliers with ISO 14001 certification for environmental management. Key specifications to verify include: purity (99.9% minimum for most applications), dimensional tolerance (±2mm standard), and surface cleanliness (free from excessive oxides). Bulk purchases (20+ metric tons) typically secure 10-15% price discounts. Consider regional logistics - lead's weight makes transportation costs significant. Many buyers opt for local smelters or regional distributors. For radiation shielding applications, request mill test reports confirming homogeneity and absence of voids.
