Description: Solders PSr are the solders with silver content from 1,0% to 72,0% having the increased heat and electric conductance, high plasticity, allowing to carry out heating by various ways in various environments and also to receive the strong connection anticorrosive with high coefficient of resistance on a gap. Materials of the index PSr Silver solders use when high temperature fuse above 400⁰C. Specific electrical resistance of solder is 90 – 120 Ohm. Density 8500 – 10000 kg/m3. Thermal capacity 18 – 26 J/kg*degrees. The details soldered to the help of silver solders well transfer dynamic loads, vibration and high temperature. It can work in hostile environment.
Normative documents: Solder is produced according to GHOST 19746-2015 (19739-2015).
Product Form:
- wire;
- sheets with various thickness.
