Technical characteristics

Lead-tin solders brand Possu25−2 increased the percentage of antimony belongs to the so-called soft solders, the melting temperature does not exceed 260 °C. a higher percentage of antimony provides resistance to surface oxidation in the zone of soldering/tinning. At the same time increases and the heat resistance (100°C). During the deforming processing of the solder it will not increase its strength characteristics. The solder connection is formed more slowly in comparison with the alloys containing a higher percentage of tin,

Application

Used for permanent connection of the various components of electrical assemblies, as well as for decorative cladding of flat surfaces. Consider the alloy is also used for tinning and soldering metal and galvanized products. Widely used in household appliances, heating appliances, refrigerators, widely used in the automotive industry.
