  • Guidelines for Selecting the Right Brazing Alloy
    that are to be heat treated may require either high- or low-temperature brazing alloys. If the braze is completed first, a high-temperature brazing alloy is called for to withstand the temperatures used during the heat treating process. An example would be joining of low alloy carbon steels with copper...

  • Paste or Preforms, the Brazer's Question (.pdf)
    atmosphere is typically neutral to reducing in nature. The. atmosphere in the furnace usually contains significant amounts of Hydrogen and Nitrogen that allow high. temperature brazing to be accomplished without oxidation or minimal to no flux. A copper braze paste consists of copper powder blended...

    . including pastes, slurries, liquids, and powders. These. fluxes, however, typically require a separate. application on the assembly to be brazed prior to. heating. The application of external flux when brazing. with solid wire is typically performed manually by an. operator prior to brazing. The solid...

    been used to produce seals and circuitry for alumina, beryllia, and mullite. Active metal brazing: Adding titanium, zirconium, or hafnium to standard silver-based braze alloys forms an activated alloy. By firing such an alloy onto ceramic surfaces at 800 to 1,000 C in vacuum or argon, the braze...
  • Corrosion-Resistant Braze Joints (.pdf)
    Nickel-base braze filler metals are widely used for brazing high-temperature plate-type heat exchangers and metallic catalytic converters in automotive applications. The recent emission/gas regulations and the development of efficient exhaust-gas recirculation (EGR) coolers by the automotive...

  • Refractory Metals
    electrode vacuum-arc melting of alloys. Cutting tools and parts that must resist severe abrasion are often made of tungsten carbide. Tungsten-carbide chips or inserts, with the cutting edges ground, are attached to the bodies of steel tools by brazing or by screws. The higher cutting speeds and longer...
