Classification

A low alloyed group of lead alloys will insignificant additions of Cu, Fe, Sb, Cd, Ca or Sn, in those concentrations that do not reduce corrosion resistance and significantly increase the durability and creep strength. A highly alloyed group of lead alloys will contain in a large number elements that increase the hardness, antifriction properties, strength, lowering the melting point of lead, and also its shrinkage during casting. Supplier Avlob offers to buy any non-ferrous metal at a bargain price. The price is the best in this segment of rental.

Corrosion resistance

Lead itself and many of its alloys, not counting those containing more than 0.1% Mg, Ca, K, Na or Li, have high corrosion resistance in water, air and most inorganic dilute acids. Lead is stable in concentrated acetic, chloroacetic and citric acid. In the presence of oxygen, the resistance to organic acids decreases. Chlorine (up to 100 ° C), sulfur dioxide and hydrogen sulfide, lead alloys have little effect.

Doping

Low-alloyed lead rolled products are stable in a humid environment, in solutions of salts of coal, sulfuric and silicic acids. Of all the elements used for lead doping, only Te and Ca act on hardening during plastic deformation. Doped with other elements, lead, because of the low recrystallization temperature, can soften during pressing, rolling, drawing, etc., processing methods that are carried out in the cold state. Strongly increase the long-term strength, the creep limit, the resistance in sulfuric acid and the temperature of recrystallization of the tellurium additive. When 0.05% Te is introduced, lead losses in sulfuric acid decrease tenfold.

Application

Lead alloys containing Cu (0,04−0,08%), Te (0,03−0,06%) and Sb (0,5−2,0%) are used in the production of pipes, sheets and other semi-finished products, intended for lining baths, pipelines and similar acid-proof equipment. Alloys doped with Ca (0,03−0,07%), Te (0,04−0,06%), Sb (0,4−0,8%), Sn (1,0−2,0%). Used for the shells of power and low-voltage cables. The fusible double, triple lead alloys are characterized by the most complex eutectic composition with Sn, In, Bi, Cd, Hg and Sb. For corrosion protection of iron and before starting the filling of bearing shells, use a special half-lead, which is a lead alloy doped with 0.5−1% Sn or Zn.
