Product Usage Silver brazing flux powder can work together with silver based brazing filler metals on copper, copper alloy,stainless steel, nickel alloy, carbide steel, and diamond PCD at the temperature range of 550-850°C in frame brazing, high frequency brazing, electrical resistance welding, furnace brazing, and so on Physaical Description White powder, density ≤ 150um Standard JB/T6045-92 Components KF ;KBF4 ;B2O3 ;Fluoroborate ;Borate ;Activity Agent. Preparation before brazing operation Brazing Opration Two major utility process could be applied. One is to mix the flux powder with water to form a thick paste(mixing rate is 100g powder with 35ml water).The paste should then be brushed onto the joint surfaces before brazing. The other option is to dip a heated brazing rod into powdered flux. The flux powder will attached on the rod immediately. Suitable gap for joint is 0.01-0.05mm.Do not overheat the alloy and flux at the brazing area, and heat gradually and evenly using a neutral flame Opration after Brazing Any or all residue should be removed by hot water .Or it can be soaked in the citric acid Storage Keep it in dry and cool place.
