Hard solder
Solder alloys have a melting point of over 425°C and mechanical strength of at least 150 MPa. Compositions with a tensile strength of up to 500 MPa are used for particularly demanding applications. They are used in cases where soldered products are subjected to increased mechanical and / or thermal loads. The main component of brazing alloys are formulations with silver, the percentage of which ranges from 2 to 15% depending on the solder grade. Many silver-containing brazing alloys are self-fluxing: the formation of a protective coating between the items to be joined and the surrounding atmosphere. Oxidation of the soldered seam is not possible in this case.
Zinc admixture
Solid solders also contain zinc in many cases. Depending on the amount of zinc in the solder, the color of the alloy may change. Zinc-containing brazing alloys are used when brazing steels and alloys with elevated melting points. This includes bronze, brass and a number of other materials.

General characteristics of hard solder
The temperatures at which the most commonly used hard solders crystallize are shown in the table below:
Solder grade | t° liquidus | t° solidus | Density, kg/m3 | Materials for which the solder is used | Fields of application |
PSr-2.5 | 305 | 295 | 11000 | Copper, its alloys, stainless | For soldering of external parts |
PSr-3 | 305 | 300 | 11300 | and carbon steels | and assemblies of electric-vacuum devices |
PSr-15 | 810 | 635 | 8300 | ||
PSr-40 | 605 | 595 | 8400 | ||
PSr-45 | 725 | 600 | 9100 | ||
PMC-Zv | 950 | 825 | 7700 | Brass, containing not more than 68% copper |
