Bismuth solders

Bismuth solders


A solder is a metal or an alloy by which a metallic compound is made in a molten state. The melting point of the solder should be lower than that of the products to be mounted. Later, after cooling down, it will give a lasting connection.


Chemical composition of solders (%)
Solder Sn Sb Pb
POSSU-40−2 In the range from 39 to 41 From 1.5 to 2 rest
POSSU-30−2 In the range from 29 to 31 From 1.5 to 2 rest
POS-40 In the range from 39 to 41 From 0.005 to 0.5 rest
POS-61 61 From 0.005 to 0.5 rest
POS-30 In the range from 29 to 31 From 0.005 to 0.5 rest

The most popular are solders tin-lead brands PIC. The numerical value: 30, 40, 61, etc., reflects the percentage of tin in the alloy.


When assembling couplings using PIC, the connection of the cable strands, the metal sheaths of cables with aluminum, the ends of the tips, lead or brass couplings, ground the metal shells, shields, cable armor in accordance with GOST 1499−70 standards .

— PIC 40 — brazing of brass, iron and copper wires.

— POS30 — brazing of brass, copper, iron, zinc and galvanized sheets, tinplate, radio equipment, electrical wire bandage and flexible hoses.

— PIC 61 — filigree soldering of the finest wires. The high content of tin in it reduces the melting point of the solder.

According to TU 48−0220−62−94, the solder of the brand POC36 contains: zinc — 63%, tin — 36%. It is used to finish the tips, soldering the conductors of cables, it solder metal cable sheath with lead, brass and aluminum couplers; Earth shields, shells and armor cables.
