Spherical Solid High Purity Lead Beads

Updated: 2026-07-18

Overview

Solid spherical high-purity lead beads are precision-manufactured spherical lead components with a typical purity of 99.9% or higher. These beads are produced through a specialized casting or rolling process to achieve uniform size and shape, making them ideal for applications requiring consistent weight distribution or radiation shielding. Lead beads are favored in industrial and scientific settings due to lead's exceptional density (11.34 g/cm³), which is higher than most common metals. The spherical shape ensures minimal air gaps when packed, enhancing their effectiveness in shielding applications. High-purity variants are particularly valued in sensitive environments where impurities could compromise performance.

Physical and Chemical Properties

High-purity lead beads exhibit a dull gray metallic luster and are highly malleable, allowing them to deform under pressure without fracturing. Their density makes them effective for weight-dependent applications, while their low melting point (327.5°C) facilitates recycling and reprocessing. Chemically, lead is resistant to corrosion from sulfuric acid and other chemicals, but it reacts with nitric acid and acetic acid. The beads are insoluble in water but can oxidize over time, forming a protective layer of lead oxide. Proper handling is essential to prevent lead dust, which poses significant health risks.

Main Applications

These lead beads are widely used in radiation shielding for medical (e.g., X-ray rooms) and nuclear industries due to their ability to absorb gamma rays and X-rays. Their spherical shape allows for efficient packing in shielding containers or flexible barriers. In ballistics, lead beads serve as projectiles or shot in ammunition. Industrial applications include counterweights for machinery, vibration damping, and balancing components in aerospace and automotive sectors. Their uniformity and density also make them useful in calibration weights and fishing sinkers.

Safety and Storage

Lead is a toxic heavy metal, requiring strict safety protocols. Handling should include gloves, masks, and ventilation to avoid ingestion or inhalation of lead particles. Work surfaces should be cleaned regularly to prevent dust accumulation. Storage recommendations include keeping the beads in sealed containers in a dry, cool environment. Avoid contact with acids or oxidizing agents. Disposal must comply with local hazardous waste regulations, and recycling is preferred to minimize environmental impact.

B2B Procurement Guide

When procuring high-purity lead beads, verify the supplier's certification for purity (≥99.9%) and consistency in diameter tolerance (±0.1 mm). Request material test reports (MTRs) to confirm composition and absence of contaminants. Bulk pricing is typically negotiable, with discounts for orders exceeding 1 ton. Consider logistics: lead is heavy, so shipping costs may be significant. Ethical suppliers should provide evidence of responsible sourcing and compliance with environmental regulations like RoHS and REACH.
