Abstract

Fluxul pentru lipire tare sub forma de pulbere, conform inventiei, este constituit din Na2B4O7, B2O3 si CaF2. în scopul extinderii gamei de cuplare cu aliaje de lipire, fluxul contine 18...21% Na2B4O7, 65...67% B2O3 si 14...16% CaF2.The powder hard soldering stream according to the invention consists of Na2B4O7, B2O3 and CaF2. In order to extend the bonding range with soldering alloys, the flux contains 18 ... 21% Na2B4O7, 65 ... 67% B2O3 and 14 ... 16% CaF2.
