  • Guidelines for Selecting the Right Brazing Alloy
    There is a wide range of brazing alloys on the market, and for many applications a number of them will do the job. The more specific the technical and economic requirements, the more obvious the correct choice becomes. There are many choices that affect the integrity of the assembly. Some
  • Brazing of CMSX-4 with a Boron- and silicon-Free Ni-Co-Zr-Hf-Cr-Ti-Al Brazing Alloy
    In this study, a new boron- and silicon-free brazing alloy containing Ni-Co-Zr-Hf-Cr-Ti-Al was used to join CMSX-4 under three conditions. The resultant joint interface microstructure and hardness of the constituents were evaluated and are reported here. It was found that by using a combination
  • Seven Steps to Successful Brazing
    choice. The second major consideration in joint design is joint clearance, i.e., the distance between the faying surfaces. Because brazing works through capillary action and joint clearance defines the capillary, this is a critical consideration. For most brazing alloys in the B-CuP and B-Ag families
  • Brazing Processes
    not oxidize at the brazing temperature or can be protected from oxidation with a flux. The most commonly used filler metals include aluminum-silicon alloys, silver-base alloys, and copper-zinc alloys. Flux is required with these filler metals unless protective atmosphere is used. Self-fluxing

    alloys don't lose strength after brazing. * Brazing pastes and foils alloy with base metals to form joints. * 650 C brazing in nitrogen forms strong, reliable heat-exchanger cores. , has a CuproBrazing Handbook, video explanation, and supplier listing. "A cooling core of copper-brass could finally
  • Vacuum Brazing of Aluminum Cold Plates and Heat Exchangers
    metal. The filler metal, also known as a braze alloy, is drawn into the closely mated parallel surfaces of the aluminum plates by capillary action. The attributes of the vacuum brazing process include uniform heating, tight temperature control, no post cleaning processes, and process repeatability.
  • Improvement in Joint Quality and Reduction of Flux Usage with Ag Based Handy One (R) Products (.pdf)
    Lucas Milhaupt Handy One brazing alloys and materials can improve braze joint quality and reduce flux usage. Handy One (R) flux cored brazing alloys have been introduced to the brazing industry in order to limit the inconsistencies seen with traditional application of brazing fluxes and solid alloy
  • Aluminum Structures
    Aluminum structures are normally brazed, welded or soldered. Braze joining of aluminum uses Si-rich Al alloys that have brazing temperatures ~ 25 - 50 ºC below the melting points of the base aluminum.
