    Brazing Alloys for Aluminum

    Image of Product. Front orientation. Brazing Alloys. Brazing Alloys for Aluminum.
    Join aluminum to aluminum. These alloys do not contain cadmium, so they are safer to use than alloys with cadmium and help meet industry regulations.
    BAlSi-3—BAlSi-3 alloys are good for filling in large gaps because they melt into a thicker liquid than BAlSi-4 alloys.

    Flux-Included Brazing Alloys for Tight Gaps

    Image of Product. Front orientation. Brazing Alloys. Flux-Included Brazing Alloys for Tight Gaps.
    Fill in tight gaps without needing to add flux before you braze—these alloys have flux built in. When melted, these alloys form a thin liquid that easily flows into smaller gaps than standard brazing alloys. They’re often used in the piping and automotive industry. Since they don’t contain cadmium, they’re safer to use than brazing alloys with cadmium and help meet industry regulations.
