Lead wire
Supplier — AvecGlob Company — offers lead at a reasonable price from the manufacturer in a wide range of lengths and diameters. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Technical specifications
Lead wire is a soft plastic profile, which is distinguished by increased corrosion resistance. In air, the wire changes its color from silvery-blue to gray, which is associated with actively passing oxidation processes.
Urgency of application
Lead wires and wires are highly heat resistant, and are used in any electronic circuits where a short-term temperature rise is possible.
Typical applications are connecting cables and lead cable braiding. Other products from lead wire include the wires of switchboards of high-current networks, wire winding, wires in ignition systems, gaskets for air frames, etc. Wire made of lead is also used in PVC braids, flexible power cables, irradiated wires, for screening polyethylene hooks, in suspension wires, cathodic protection cables. In mechanical systems, lead wire can be used as balances and counterweights.
Chemical composition
The composition of lead wire is regulated by the requirements of GOST 3778−98 (numerical data — in percent):

Assortment and application features
Lead wire, which is produced according to the technical requirements of GOST 1292−81 and GOST 3778−98, is produced from pigs in the range of diameters 1… 8 mm. The material is toxic, which should be taken into account in its further use.
Supplier — AvekGlob Company — offers to purchase lead wire in the required assortment of diameters and length. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
