Характеристики
Brazing flux(Soldering flux)
The important functions of sanhuan soldering flux are as follows:assisting heat conduction,clearing the oxide on the surface of parent materials and brazing materials,reducing the surface tension of soldered materials,clearing oil stain on the surface of soldered materials(parent materials),enlarging brazing area,avoiding re-oxidation,etc. It can be divided into solid(paste),liquid and gas.
The Sanhuan technical team can provide suitable fluxes according to the different needs and applications of customers.
