Product Description

Soldering fluxes are chemical compounds applied to the joint surfaces before brazing, can be classified as corrosive, intermediate or non-corrosive.
Such as: silver soldering flux powder/ paste, aluminum soldering flux powder/ paste, copper soldering flux powder/ paste.
They are all essential to use in the whole process of brazing/soldering operation.
Heating a metal surface accelerates the formation of oxides, the result of chemical combination between the hot metal and oxygen in the air.
This oxide layer has to be removed before brazing, and the formation of a new oxide layer has to be prevented or they will inhibit the filler metal from wetting and bonding to the surfaces.
Brazing Fluxes play a vital role in virtually all air brazing processes.
Use of the wrong flux or a poor application technique can have a dramatic effect on joint quality.
