The PSR 40 solder
Solder is an alloy used to connect any metal parts or details. It is worth noting an important point — the solder must have a lower melting point than the joined metal. Typically, the solders used are lead, tin, bismuth, copper, zinc etc.
Relevance
The brazing process required to obtain maximum strength of the seams on the products for as long as possible to extend their lifespan. Often use these types of alloys as solder marks AKP-15, AKP-72, AKP-5 and AKP-6. These brands of solders differ in their temperatures, but they are fairly common. It should be noted that the solder mark PSRMS-37 and PSR-3 is considered to be on the market sold the least.
The soldering process solder AKP
Since the melting point of solder is much lower than the fastened metal, then the heating time, while the main part continues to be solid, solder the AKP begins to melt and penetrate its particles in the voids of the base metal. Then, when the product fully cools down, you get a very durable single piece.
| Solders brand PSR | |||
|---|---|---|---|
| Solder | Supply | t° melting | Application |
| PSR 10 | Ingots, wire Ø 1−4 mm, rod | 830°C | Tinning and brazing of copper, brass and sheet zinc |
| PSR 12 | Ingots, wire Ø 1−4 mm, rod | 785°C | Tinning and brazing of copper, brass and sheet zinc, galvanized iron. |
| PSR 25 | Ingots, wire Ø 1−4 mm, rod | 765°C | Soldering of radio equipment, printed circuits, precision instruments. |
| PSR 45 | Ingots, wire Ø 1−4 mm, rod | 720°C | Tinning and brazing of copper, brass and sheet zinc, galvanized iron, creating a watertight seam. |
| PSR 65 | Ingots, wire Ø 1−4 mm, rod | 740°C | Tinning and brazing of copper, brass and sheet zinc, galvanized iron, creating a watertight seam. |
Classification of solder
Solders are divided into hard and soft. To soft types of solders considered those where the temperature is less than three hundred degrees Celsius. The solid solder has a melting point of more than three hundred degrees. For example, solder PSR-70, the melting temperature is 780 degrees Celsius, and the solder RPS-25 of 765 °C. There are silver solders. These alloys are marked PSRMS. Melting point PSRMS 37 is 692 °C. this means that it is possible to determine the group of hard alloys and solders.
Buy at best price
To purchase solder AKP you can in the company «AVEK global», which is engaged in metal products for many years. The solder RPS-45 has the best price, so if the temperature difference of 20−30 degrees is not a big deal, it is recommended to use solder brand Sep-45. To purchase solder AKP better from reliable vendors. Recommend that you treat this purchase very seriously, because this depends directly on the quality of the products that you plan to.
