* Aluminum base series filler metals
Brazing flux
　　The main action of brazing flux is to get rid of the film oxide on the surface of brazed metals and liquid brazing filler metals , improve its wettability to the base metal , promote the filler metals' ability to fill rapidly the brazing clearance and flow widely along the braze .The flux's melting point and the lowest temperature is a little lower than the melting temperature of brazing filler metal . In brazing , the filler metal must be melted on time as possible after the flux is melted 0,rapidly fills the clearance so that the good braze can be formed .However , the gas hole , dregs or leak may be formed in the braze if the flux is too much or the filler metal can't melt on time .
