Description

Solder ВПр11−40N is applied: for the soldering of details of aircraft engines and other high-loaded parts, providing seam strength 80% of the strength of the base material at the brazing temperature range from 980 °C to 1020 °C.

Note

High temperature solders based on Nickel is a powder with a particle size up to 250 microns, obtained by spraying in inert gases of the molten metal melted in a vacuum induction furnace.
