Products Detail
  • Product name: Copper Zinc Brazing Filler Metals

Applications and Features

The product is applied to brazing by rapid heating, such as flame brazing, high frequency brazing, resistance brazing, and is used for brazing of copper, copper alloys, steel, cast iron and hard alloys. The dirt, such as grease, oxide on the surface of brazing metals should be well cleaned before brazing. The fluxes such as powder flux, gas flux and paste flux are recommended to be used.
