    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.
