1mm Thin Lead Sheet

Updated: 2026-07-15

Overview

1mm thin lead sheet is a highly malleable and dense material primarily composed of elemental lead (Pb). With a thickness of precisely 1 millimeter, it offers an optimal balance between flexibility and structural integrity for various industrial applications. Lead sheets have been used for centuries due to their unique properties, including excellent radiation absorption and corrosion resistance. The 1mm thickness is particularly popular in applications requiring both protection and workability, such as in medical facilities and construction projects.

Physical and Chemical Properties

The 1mm thin lead sheet exhibits several distinctive physical properties. Its high density (11.34 g/cm³) makes it effective for radiation shielding, while its low melting point (327.5°C) allows for easy forming and shaping. The material maintains stability across a wide temperature range. Chemically, lead is relatively inert to many corrosive substances but reacts with acids. The thin 1mm profile provides adequate protection while minimizing weight, making it suitable for applications where space and weight are considerations, such as in mobile X-ray units or architectural installations.

Main Applications

In the medical field, 1mm lead sheets are indispensable for radiation shielding in X-ray rooms, CT scan areas, and nuclear medicine facilities. The thickness provides adequate protection against common diagnostic radiation levels while remaining workable for installation. The construction industry utilizes these sheets for soundproofing in recording studios and vibration damping in industrial settings. Other applications include roofing in historical building restoration, battery manufacturing, and as weights in various mechanical systems.

Safety and Storage

Proper handling of 1mm lead sheets requires gloves to prevent direct skin contact and potential lead absorption. Cutting or machining should be performed with adequate ventilation to avoid inhalation of lead particles. Storage recommendations include keeping sheets flat in a dry environment, separated from acids or oxidizers. For long-term storage, wrapping in plastic can prevent oxidation. Facilities using lead sheets should implement regular surface cleaning to minimize dust accumulation.

B2B Procurement Guide

When sourcing 1mm thin lead sheets, verify the material's purity (typically 99.9% or higher) and request mill test certificates. Reputable suppliers should provide documentation of compliance with international standards like ASTM B749. Consider lead time and minimum order quantities, as these vary by supplier. For radiation shielding applications, confirm the sheet's uniformity and absence of voids or inclusions. Some suppliers offer custom cutting services, which can reduce waste and installation time for specific projects.
