Kupfer-Zink-Hartlot Schweißdraht

Copper-Zinc Brazing Alloys are suitable for gas-flame brazing, high temperature brazing, salt bath dip brazing of copper and copper alloys , nickel, cast iron and hard alloys. While brazing by oxyacetylence, to heat with oxidized flame quickly can lessen evaporation of Zinc and prevent gas porosity due to over-oxidization.The optimun joint gap should be 0.025-0.1mm. Flux is also necessary for good seam. Melting range ApplicationAWS StandardChemical Analysis°C°CCuZuSuFeNiSiOtherSolidus°CLiquidus°CSw22160Bal.1——0.3—890905Melting point is about 900°C.
