Solder Psr 40
Relevance
Solder is an alloy that is used to join any parts or fragments. It is important that the solder has a lower melting point than the materials being joined. Usually, tin, lead, copper, and antimony are used for soldering. Soldering allows you to create a strong connecting seam, the service life of the product increases. How does the brazing process work? Since the melting temperature of solder is much lower, so, melted, it fills the empty spaces of the main part with its particles. Once the product has cooled, a strong connection is obtained that becomes one with the part for a long time.
PSR solders
The best selling brands are PSR 2, PSR 15, PSR 72, which are the most practical to use.
| Alloy | Fe | Ag | As | Sn | Pb | Cd | Sb | Bi | Impurities |
|---|---|---|---|---|---|---|---|---|---|
| PSR2 | ≤0.15 | 1,7-2,3 | --- | 29-31 | 61-64,65 | 4,5-5,5 | --- | ≤0.01 | ≤0.15 |
Solder PSRMC 37.5 and PSR 2.5 are less popular on the market. The classification classifies PSR solders into soft and hard. The former include those with a temperature of less than 300 °C. Accordingly, hard solder melts at t° more than 300 °C... There are technical tables of correspondence of solder PSR number and melting temperature. For example, solder PSR 72 has a melting point of 780 °C, and solder PSR 2.5 - 765 °C. PSRMC 37 is a type of silver solder. It has a melting point of about 692 °C. This means it can be classified as a hard solder.
| Alloy | Fe | Ag | As | Sn | Pb | Cd | Sb | Bi | Impurities |
|---|---|---|---|---|---|---|---|---|---|
| PSR2.5 | ≤0.15 | 2,2-2,8 | --- | 5-6 | 91-92,65 | --- | --- | ≤0.01 | ≤0.15 |
