Uses of Pure Lead and Refined Lead
There are many different uses of Lead. It may be used as a pure metal, alloyed with other metals, or as chemical compounds.
Battery
The principal consumption of Lead is for the Lead-Acid storage battery in which grid or plate is made of Lead or Lead with other metal more commonly with antimony.
Rolled Extrusions
Lead Sheet is used in the building industry for flashings or weathering to prevent water penetration & for roofing and cladding. By virtue of its resistance to chemical corrosion, Lead Sheet also finds use for the lining of chemical treatment baths, acid plants and storage vessels. The high density of Lead Sheet makes it a very effective material for sound insulation purpose. Lead clad steel has also found use in radiation shielding.
Lead pipes due to its corrosion resistant properties are used for carriage of corrosive chemicals at chemical plants. Also Lead pipe of appropriate composition is still extruded for cutting into short length ‘sleeves’ for use in the jointing of Lead sheathed cables.
Pigments
Used extensively in paints, although recently the use of Lead in paints has been drastically curtailed to eliminate or reduce health hazards. White Lead, 2PbCO3 Pb(OH)2, is the most extensively used Lead pigment. Other Lead pigments of importance are basic Lead sulfate and Lead chromates.
Cable Sheathing
Because of its high ductility, good extrusion ability, relatively low temperature & excellent proven corrosion resistance when in contact with a wide range of industrial and marine environments, soils and chemicals, Lead Alloys are used extensively as sheathing materials for high voltage power cables.
Ammunition
Use of ammunition with Lead Bullets, which are commonly used in sport shooting with small arms.
Lead alloys
Lead forms alloys with many metals. Alloys formed with tin, copper, arsenic, antimony, bismuth, cadmium, and sodium are all of industrial importance.
Lead is used to make bearings, solder, antifriction metals, and type metal.
Soft solders are largely Lead-tin alloys with or without antimony while fusible alloys are various combinations of Lead, tin, bismuth, cadmium and other low melting point metals.
Shot Lead is an Alloy of Lead, Antimony, and Arsenic. Lead Foil is made with Lead alloys. Lead is added to brass to reduce machine tool wear.
