Harris Brazing Flux Paste 6.5 oz

This Harris brazing flux comes as a white paste in a 6.5 oz brush-cap bottle. It is formulated for high-silver alloys and carries AWS classification FB3-A. The product is new and intended for professional brazing applications where a paste flux is preferred.

Active temperature range 1050 to 1600 F

The flux becomes active at 1050 degrees F and remains effective up to 1600 degrees F. This range determines whether the paste suits your specific brazing procedure and the melting point of the filler metal you are using. Verify that your process operates within these limits before purchasing.

For technicians brazing high-silver alloys

This flux suits technicians who need a paste-form product for high-silver brazing alloys within the stated temperature window. It is not for users who require a flux for lower-temperature soldering, higher-temperature welding, or different alloy families such as copper-phosphorus or aluminium. The brush-cap bottle may also be unsuitable for automated dispensing systems.

Questions about this item

What does the 1050 to 1600 F range mean when I am brazing?

The flux becomes active at 1050 F and stays effective up to 1600 F, so it protects the joint during high-silver alloy brazing within that window.

What does the AWS FB3-A classification tell me about how I can use this flux?

AWS FB3-A certifies the paste for brazing with high-silver alloys and confirms it meets the industry standard for flux performance in that temperature band.

How does the 6.5 oz brush-cap bottle work when I need to apply flux in a tight joint?

The built-in brush cap lets you dab paste directly onto the joint without a separate brush, and the 6.5 oz volume covers many small to medium assemblies.
