Today produced a range of tin solders, which are widely demanded by electrical engineering, electronics, instrumentation, installation of HVAC equipment. It should be noted that the advantage of tin solders is a small price to pay. They are very practical to use plastic, giving high durability, soldering, distinguished corrosion resistance. Used to connect any non-ferrous alloys.
The composition of tin solders tin also includes such low-melting metals such as lead antimony, alloyed with zinc, aluminum, cadmium. The strength of soldering is 8 kg/mm2 and is directly proportional to the percentage of tin in the solder. The presence of antimony also enhances the ration, but only when connecting copper parts. When soldering brass parts antimony such influence does not already have a soldering iron — even lowers the strength of the contact. Zinc increases the corrosion resistance of the contacts. The high content of zinc requires additives such as cadmium or silver. Solders with 10−40% zinc, is typically used for the treatment and brazing of aluminum alloys by ultrasonic method. With the increase of zinc content melting point of the solder increases.
Soft solders are produced in the tubules placed inside the flux and rarely in the form of wire. The range is so-called paste is powdered solder with flux. It should be remembered that the application of the paste causes a number of limitations. For example, zinc chloride is quite hygroscopic and it remains on the soldering may lead to corrosion. Prohibited its application as ammonia during installation of electrical sensors, in connection with the emergence of a Copperhead on the copper contacts, which can lead to distorted readings. When soldering tin solder flux is rosin.
