Lead is a chemical element with atomic number 82 and symbol Pb (from the Latin plumbum). It is a heavy metal with a density exceeding that of most common materials; it is soft, malleable, and melts at a relatively low temperature. When freshly cut, it has a bluish-white tint; it tarnishes to a dull gray upon exposure to air. Lead has the second-highest atomic number of the classically stable elements and lies at the end of three major decay chains of heavier elements.

Material Notes

Lead Sputtering Targets, Purity is 99.995%; Circular: Diameter <= 14inch, Thickness >= 1mm; Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm. This material may require special ramp up and ramp down procedures. This process may not be necessary with other materials. Targets that have a low thermal conductivity are susceptible to thermal shock.
