Lead alloys

Technical characteristics

Lead is the 82nd element of the 4th period of the Mendeleev table, where it is designated Pb. It is a soft metal with a bluish-gray color. It has a face-centred cubic lattice, it is excellent forging material due to its plasticity and ductility. The metal melts easily at a temperature of only 327.5°С. The boiling point is 1740 °C. It has low thermal conductivity. The surface is covered with an oxide film which protects the metal from the adverse effects of the environment. It is extracted from intermetallic ores. The main suppliers are USA, EU, Korea, China. Today the price per kilogram of lead on the world market is 1.5 cu.

Lead alloys.

They are conventionally divided into two categories - high-alloyed and low-alloyed. The first category includes lead alloys with various special additives, which increase the metal's resistance to external influences. Such additives can increase the antifriction properties, change the melting point and the degree of shrinkage. Low alloyed alloys include compounds of lead with tin, nickel, antimony, cadmium and copper. These alloys increase the corrosion resistance of lead in acidic environments and conditions of high humidity. Additions of antimony or copper allow the alloys to be used in the production of construction materials, such as sheets, fittings and pipes. Tin additives make it possible to manufacture low-voltage and power cables. Lead in combination with other metals, gets a number of advantages. For example, the strength is increased, which allows it to be used for joining or soldering pipelines.

Casting Lead

This is a fairly complex process that cannot be replicated at home. Casting technology involves a well-ventilated large room in which the liquid melt is poured into separate molds and kept at a special temperature and a certain pressure. I would like to point out that lead fumes are toxic. Poisoning can be quite serious, up to and including death. But, despite this, it is impossible to do without lead today.


The use of lead began since ancient times, for example, in the past it was bought to make your own stamp, as to put an imprint on its surface is easy enough. Today it is used in the manufacture of seals for sealing safes, premises or freight cars. It is most often used by the industrial chemical, construction and energy industries. To this day, it remains indispensable for the production of fuel detonators and car batteries. An important factor is its low cost, physical and chemical properties, as well as the possibility of recycling when the batteries are out of service.


Note that it is possible to dispose of such products only by following the norms of SNIP. The lowest prices are for scrap lead cable. Will accept the material only if it is clean. Considerably more expensive is the reception of scrap dressed lead, though, if it is without foreign inclusions, which reduce the price. The most expensive price is paid for scrap lead typography.

Sheet lead.

Actively used in construction. It is suitable for roofing buildings, fixing fireplace or stove pipes. It is used in the equipment of X-ray rooms. For repair work in a private home, you can choose sheet lead to cover the roof. Lead is also bought most often in sheet form. It is the most versatile and most practical. Sheet can be used, for example, to cover a door. Such a treatment will make the door bulletproof. It is clad in military vehicles, submarines, and also used as bibs on diving suits.
