Lead wire S2 F3.0 mm is produced in accordance with GOST 1292-81, GOST 3778-98, GOST 3778-77. The Soyuz group of enterprises produces, sells and supplies lead wire of the following grades: C1, C2, C3, C3C, CCu2, CCu. Lead wire is an indispensable element of various technical devices and is used in electrical engineering, the transport industry, special alloys can even be used in the watch industry, medicine and everyday life. In addition, lead wire is a raw material for the production of other products. Due to the low mechanical strength that lead and its compounds have, lead wire is obtained by pulling solid metal through a die. At the same time, the density of lead is 11.34 (refers to heavy metals). The diameter of the lead wire can vary from 0.6 to 10 mm, which the lead plant agrees with the consumer.
Depending on the manufacturing method, lead wire is divided into soft, semi-hard, hard and extra hard.
Mechanical strength is normalized by the temporary withstand resistance and varies within 290-720 MPa depending on the type of wire.
Lead wire must have a clean, smooth surface.
Lead wire is a product of rolled lead with a large length, with a circle, less often an oval or a square in cross section. In appearance - lead cord, thread. For ease of transportation, lead wire is rolled into coils or coils, or wound on coils. To prevent the coiled wire from breaking, kinks, twists, knots and sharp bends in the cord should be avoided.
The melting point of lead and, accordingly, wire is 327 degrees Celsius.
Properties and characteristics of lead wire:
- plasticity and softness;
- passivity in relation to sulfuric and hydrochloric acids;
- high resistance to corrosion;
- ease of use;
- low price of lead wire.
Quality lead wire should have a smooth, even and clean surface. Quality control includes checking the product for fracture (each batch is examined, with a diameter of 3 mm or more - two rolls). There should be no visible inclusions, cavities or other defects on the fracture.
The weight of one running meter of elliptical lead wire with a diameter of 9 * 12 is 0.9523 kg, and 12 * 18 is 1.55 kg. Products of this form are most often used for waterproofing between sections of free space tubing rings. The abbreviated name of lead waterproofing wire is GPS.
Lead wire production
Due to the low strength of lead and susceptibility to the mechanical action of lead, the wire is made not by the usual drawing, but by forcing solid lead through a die (a special form of high-strength material). The chemical composition must comply with GOST 3778-98, round lead wire is produced in accordance with TU 48-21-792-85, and elliptical - in accordance with TU 48-21-791-85. According to these regulatory documents, the diameter of the product can vary from 0.6 to 10 millimeters, but wire is also available in other diameters. Elliptical lead wire is produced in sizes 9*12 and 12*18 mm. By execution, lead wire of special hardness is distinguished, soft, hard and semi-hard. The mechanical strength in this case can be in the range from 290 to 720 MPa.
Lead wire S2
It is produced from primary lead with high chemical purity, which, according to GOST 3778-98, contains 99.985% pure lead and only 0.015% impurities (copper, iron, zinc, silver, arsenic, tin, antimony, beryllium). Lead wire C1 has a very high resistance to corrosion processes and good ductility.
Application of lead wire
This type of lead metal is widely used in the transport industry, electrical engineering. Wire made from some lead alloys can be used in medicine or in the manufacture of watches, in everyday life. Lead wire also serves as a raw material for the manufacture of many other products.
So, wire made of lead and its alloys is used:
• in the transport sector;
• connection of pipelines, chasing of joints of tubing cast-iron lining (lead hermetically and evenly fills the seam);
• in everyday life (manufacturing sinkers for fishing, flies);
• in the electrical industry;
• in the manufacture of watch mechanisms;
• glass industry;
• in medicine.
Properties:
Lead has a high melting point. Resistant to corrosion and most acids. Due to these properties, this metal is used in various industries. Inexpensive. Relatively easy to get. Therefore, it is popular as a building material.
The material is very supple and soft. Therefore, for the manufacture of products from it, including wire, it is enough to push a solid billet through a die. The shape of the product depends on the shape of the die. Lead wire of square section is practically not used in industry.
Release
The material is manufactured with strict observance of all requirements of technology.logical process on specialized equipment. Due to the fact that lead itself is not very strong, the wire from it is made not by drawing, but by forcing through a special form of the desired diameter.
There are soft, semi-hard or hard lead wire. It is supplied in coils, spools or reels.
This type of rental is different:
- excellent plasticity;
- resistance to corrosion and external influences;
- increased acid resistance;
- durability and practicality.
