Aluminum Brazing

Use at high temperatures when brazing massive assemblies. AMCO 30 is highly active chemically and produces good flow of the filler alloy. Well suited for brazing aluminum 1100 and 3003 parent metals, 4043 brazing alloy, and Nos. 11 and 12 brazing sheets.

Working temperature: 1100-1140F.

A high-activity flux for brazing aluminum and normally used with type 4047 filler alloy. AMCO 33 is recommended for use on all brazeable aluminum including 3000, 5000 and 6000 series using 713, 714, 716 and 718 filler alloys. This flux can be used for oxyacetylene or oxyhydrogen torch brazing, furnace brazing, and automatic flame brazing. AMCO 33 has a lower melting point than AMCO 30 and is, therefore, useful with low melting-point alloys. It has proved its reliability in industry for more than four decades.

Working temperature: 1080-1140F.
Conforms to AMS 3412F.

Dip Brazing

An all-purpose dip brazing flux that is well established in the industry with years of excellent service. It is a specially compounded flux suited for brazing all brazeable aluminum alloys, including wrought products, forgings, extrusions and certain castings. The same composition as AMCO 341 but with a finer particle size.

Working temperature: 1050-1150F
Conforms to AMS 3415E and AWS CLASS FB1-C

An all-purpose dip brazing flux that is well established in the industry with years of excellent service. It is a specially compounded flux suited for brazing all brazeable aluminum alloys, including wrought products, forgings, extrusions and certain castings. The coarse particle size of this flux permits makeup additions to the dip pot with less dusting.

Working temperature: 1050-1150F
Conforms to AMS 3415E and AWS CLASS FB1-C

AMCO 501 is a specially compounded low-melting dip brazing flux particularly suited for brazing all the common brazeable aluminum alloys. It is a low-fuming flux with a low melting range, which provides for better drainage for parts being brazed and, therefore, results in less flux dragout than with most other dip brazing fluxes. AMCO 501 possesses good activity over a wide brazing temperature range. Because AMCO 501 has excellent chemical stability, the flux bath should not require chemical additions other than new flux for dragout replacement under normal operating conditions.

Working temperature: 1050-1150F
Conforms to AMS 3415E
