Featuring Holtite Alloys and Miter-Al-Braze Alloys for Aluminum Metal Joining

Brazing is a metal joining process whereby a filler metal is heated above the melting point and distributed between two or more close fitting parts by capillary action. The filler metal is brought slightly above its melting ( liquidus ) temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal ( know as wetting ) and is then cooled to join the workpieces together. It is similar to soldering, except the temperatures used to melt the filler metal are higher for brazing.

A variety of alloys are used as filler metals for brazing depending on the intended use or application method. In general, braze alloys are made up of 3 or more metals to form an alloy with the desired properties. The filler metal for a particular application is chosen based on its ability to: wet the base metals, withstand the service conditions required, and melt at a lower temperature than the base metals or at a very specific temperature.

Applications: Joining material within the Aluminum family of alloys.

Forms: Cast Strips or Powder, special shapes available upon request.

    MAB REGULAR
    MAB REGULAR
    Belmont MAB ( Miter-AL-Braze ) rod is an effective and efficient joining material. Our regular version is harder and stronger than the MAB II Hi-Test that we also offer. Most users find the No. 1 Regular to be effective for general purposes. The strength of an MAB joint in many cases is as great as that of a brazed joint and this material is most commonly used for joining aluminum pieces.
    Forms:
    • 1/8" x 18" Cast Strip
    • 1/8" x 12" Cast Strips
    • 1/8" x 18"Cast Strips
    • 3/16" x 18" Cast Strips
    • 3/32" x 18" Rods
    • 3/32" x 36" Cast Strips

    MAB 11 HIGH TEST
    MAB 11 HIGH TEST
    Belmont MAB ( Miter-AL-Braze ) rod is an effective and efficient joining material. While not as hard and strong as our No. I Regular version this item was developed to provide extra ductility. MAB II Hi-Test has often been used by aluminum window manufacturers to join mitered corners, where some bending is required during installation. The strength of an MAB joint in many cases is as great as that of a brazed joint and this material is most commonly used for joining aluminum pieces.
    Forms:
    • 1/8” X 18” Cast Strip
    • 3/32” X 18” Cast Strip

    Holtite Alsil Grit
    Holtite Alsil Grit
    This Fine mesh Brazing Solder has a lower melting temperature than our other Holtite versions and is Aluminum & Silicon based.
    Forms:
    • 100 Mesh & Down Powder
    • 30 - 60 Mesh Granular
    • 40 - 100 Mesh Granular

    Holtite Fine Gray Solder
    Holtite Fine Gray Solder
    This solder filler has a lower melting temperature than our brazing alloys. In solder joints the base metals will typically be much stronger than the solder following the soldering process.
    Forms:
    • 40-120 Mesh
    Belmont Product Code 4508
