Lead Introduction Lead is one of the most stable metals. The processes used in its production are essentially the same as those used for zinc. Lead sulfide ore is converted into lead oxide which is reduced to metallic lead by a continous process in a blast furnace. The relatively low cost, easy workability and good environmental resistance of lead have made it in the past an obvious choice for sheathing purposes.
Alloys improve creep and fatigue properties, but reduce corrosion resistance.
Increases strength and hardness and improves castibility. However it makes the material more difficult to weld or solder and lowers melting point, reducing the upper service temperature limit. Increases hardness and strength and improves castibility. Dispersion Strengthening of lead with its own oxide provides a means of improving stiffness, fatigue strength and creep resistance of pure lead and dilute alloys, without impairing significantly corrosion resistance. Lining, pip, sheet etc., used in the manufacture, handling and storage of corrosive chemicals in the chemical industry.
