• Non-corrosive flow
It is usually a compound of borax and boric acid. It is efficient when the welding temperature is higher than 800 ° C.
• Flow enabled
Most fluxes commonly used for welding with silver of this type.
It has high oxidation removal capacity due to the addition of compounds such as potassium fluoride, potassium chloride and sodium fluoride to the borax and boric acid compound.
