Silver solders PRS
Foreign stamps
Silver solders, such as Rothenberger, Rolot S2 are complex multi-component composition based on copper. contain 1,5−2,5% Ag, 5,9−6,5% phosphorus, plus alloying additives such as cadmium, tin and several others that improve the quality of the connection. Melting point: 650−810°C. are Used for materials such as brass, copper, bronze. For brass and bronze recommended flux paste LР5. But such alloys are not suitable for iron-copper-Nickel alloys.
Solders RPS
The most sold following brands: RPS 2, RPS 15, RPS 72, which are most practical in application.
| Alloy | Fe | Ag | As | Sn | Pb | Cd | Sb | Bi | Impurities |
|---|---|---|---|---|---|---|---|---|---|
| PSR2 | ≤0.15 | 1,7−2,3 | --- | 29−31 | 61−64,65 | 4.5 to 5.5 | --- | ≤0.01 | ≤0.15 |
Solder PSRMS 37.5% and 2.5 less popular in the market. Classification divides the solders RPS at soft and hard. It first considered such a temperature less than 300 °C. Accordingly, the brazing alloy melts at t° more, 300°C… There is a technical table, the number of solder AKP and the melting temperature. For example, solder 72 AKP has t° melting 780 °C, and solder the AKP 2.5 — 765 °C. the Solder PSRMS 37 refers to the varieties of silver solder. It has t° melting at about 692 °C. And therefore can be classified as hard solders.
| 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 |
Dignity
Withstand high temperature. For the connection of copper to copper no flux is required. Do not cause corrosion, does not harm the environment, have high fluidity, high deformation characteristics, applicable to soldering systems, is subject to considerable mechanical or thermal loads.
Application
Ideal for capillary-slot soldering when joining copper pipes in cold and hot water systems (liquid natural gas) and also for installation of refrigeration systems, air conditioning systems and oil lines. These solders are specially designed for capillary-slot soldering copper tubing without the use of fittings.
Solder HTS
Used when you need to perform work on the aluminium by soldering. Allows you to work, without resorting to the use of flux, which is very convenient. since aluminum is covered with a dense oxide film, but only the solder hts 2000 is able to provide a quality weld. This solder is very practical. For low temperature welding of non-ferrous metals using the gas burner, for example, oxy-acetylene, propane, or MAPP. Accessibility and ease of use make it the leader among all known solders for the soldering of non-ferrous metals.
