Flux-containing brazing agent brazed at low temperature

Disclosed is a flux-containing brazing material, which is used to braze the same or different kinds of metal members with each other at low temperatures. The flux-containing brazing material includes a mixed powder, comprised of Zn alloy powder, containing 10 to 40 wt % of Al or Al and Si, and remaining Zn, and 10 to 40 wt % of cesium fluoride-based flux powder on a basis of the Zn alloy powder. The mixed powder is subjected to powder forging and extruding processes to form a three-dimensional flux. The flux-containing brazing material is advantageous in that the Zn alloy and flux powders are mixed with each other and machined to form the three-dimensional flux, thereby simplifying a brazing process because a flux coating process is omitted during the brazing process. The brazing quality is improved because the flux content in the brazing material is properly controlled.
