Silver solder PSr

Description: PSr solders are silver-containing solders with silver content from 1.0% to 72.0%, featuring enhanced thermal and electrical conductivity, high ductility, allowing heating by various methods in various environments, and providing a strong, corrosion-resistant joint with high tensile strength. PSr grade materials create strong permanent joints between parts made of various steels, copper and its alloys, silver, and other refractory metals. Silver solders are used for high-temperature brazing above 400°C. The resistivity of the solder is 90 – 120 Ohm. Density is 8500 – 10000 kg/m3. Heat capacity is 18 – 26 J/(kg·°C). Parts soldered with silver solders withstand dynamic loads, vibration, and high temperatures well. They can operate in aggressive environments.

Regulatory documentation: PSr solders are manufactured in accordance with GOST 19738-2015, PSr wire — GOST 19746-2015, PSr strip — GOST 19739-2015.
