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.
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.
The composition of lead wire is regulated by the requirements of GOST 3778−98 (numerical data — in percent):
|Marking of the brand||Chemical composition|
|Sweets, not less than||Mass fraction of impurities, not more than|
|Silver||Copper||Zinc||Bismuth||Arsenic||Tin||Antimony||Iron||Magnesium, calcium and sodium in total||Total|
|C0||99.992||3 x 10 -4||5 x 10 -4||0,001||0.004||5 x 10 -4||5 x 10 -4||5 x 10 -4||0,001||0.002||0.008|
1 In lead grade C0, intended for the production of groundworm, the mass fraction of the chromium impurity should not exceed 0.0001%. The mass fraction of chromium in lead grade C0 is guaranteed by the manufacturer.
2 Lead of grades С1С, С2С and С3С is made at the request of the consumer.
