Product Overview
Our radiation shielding lead bricks are manufactured from high-purity electrolytic lead with a purity of ≥99.9%, fabricated through precise melting, pressing and pouring processes. As ultra-high-density functional materials, they are professionally developed for radiation shielding, industrial counterweight calibration and sound insulation engineering scenarios, featuring stable physical properties and reliable comprehensive performance.
Core Performance Advantages
1. Outstanding Radiation Shielding Capacity
Boasting a high density of 11.34 g/cm³, the lead bricks deliver powerful attenuation performance against X-rays and gamma rays. Practical test data verifies that a 100mm-thick lead brick barrier can block over 90% of 100kV X-rays. Its unit-volume shielding efficiency is three times higher than that of conventional concrete, which significantly reduces wall thickness requirements and cuts overall construction costs for radiation protection spaces.
2. Superior Stability & Long Service Life
The product features exceptional acid and alkali corrosion resistance, as well as excellent anti-aging performance against long-term radiation exposure. Under standard operating environments, its service life can exceed 30 years. Optional surface treatments including galvanization and epoxy coating are available to further enhance durability, enabling stable operation in high-humidity, high-temperature and other complex working conditions.
3. Modular Design for Flexible & Efficient Construction
We provide two standard specifications: 200×100×50mm and 100×100×50mm, with dimensional tolerance strictly controlled within ±1mm. Equipped with a professional interlocking bite edge structure, the bricks enable seamless stacking and tight wall assembly. Each standard brick weighs approximately 11.3kg, perfectly balancing reliable shielding performance and convenient manual handling for on-site construction.
Key Technical Parameters
The product maintains a stable lead purity of ≥99.9% and a tested density of 11.34±0.05 g/cm³, with compressive strength exceeding 25MPa. It features consistent and stable performance across a wide temperature range of -50℃ to +80℃ with no performance attenuation. Customized products support precision tolerance control up to ±0.5mm. The surface roughness is controlled at Ra≤3.2μm, ensuring a smooth surface free of oxidation layers and slag inclusions for consistent shielding effects.
