铜-锌钎焊合金焊接杆

Description Copper-Zinc Brazing Alloy are suitable for gas flame brazing ,high temperature brazing of copper and copper alloy, nickel, cast iron and hard alloys ,During oxy-acetylene brazing , to heat with oxidized flame quickly can lessen evaporation of zinc and prevent porosity from over-oxidization. The opromum joint gap is 0.025-0.1mm. Flux is also necessary to obtain good brazing seam.
