Lead is one of the oldest metals known to man. Probably the earliest specimen is a figure from about 3000 BC found in the temple of Osiris. One of the most interesting historical applications was its general use by the Roman people for water pipes that were generally 10 feet in length. Many magnificent buildings from the 15th and 16th century still stand under their original lead roofs. Leaden ornaments, statues, and leader heads have come to us in a perfect state of preservation. Today, Lead ores are mined at a rate of more than 3 million tons a year with a market value of around US $1 billion and the world market for refined lead stands at about $15 billion.
Lead probably has more varied fields of application than any other metal. The outstanding characteristics of lead include heavy weight, high density, softness, malleability, flexibility, low melting point, low strength, low elastic limit, ability to alloy with certain other metals, lubricating properties, low electrical conductivity, high coefficient to expansion, radiation wave resistance and high resistance to corrosion under a wide variety of conditions. Lead is ordinarily selected for use because of one or more of these properties.
