Lead Powder is a granular material that consists of fine particles of metallic lead. We produce it ourselves in 30 size variations for a selection of particle sizes and distributions ideal for applications like radiation shielding, sound dampening and high-density ballasting. The heavy density and malleability of lead make it well-suited for these and other scientific, industrial and commercial uses where its unique properties can be leveraged in powder form.
