Workshop Practice: Fluxing an Aluminium Joint
Students cut two pieces of Aluminium Sheet and set them up as a T-joint. A little flux is mixed with water to a thin paste and brushed along both sides of the joint line. The joint is heated with the MAPP torch until the flux turns liquid and clear, a sign that the metal is close to brazing heat.
The Aluminum Rod is then touched to the far side of the joint, so the filler is drawn right through. Once the work has cooled, students scrub off the residue with hot water and a brush. Teachers can leave one sample unwashed to show how leftover residue marks and corrodes the surface.
Frequently Asked Questions
How is the powder applied?
Mix a small amount with water into a paste and brush it on the clean joint. The other way is to heat the rod tip and dip it into the powder, so the flux sticks to the rod. Make only as much paste as the job needs.
Does the flux residue need cleaning off?
Yes. Aluminium flux residue draws moisture and attacks the metal if it is left on. Wash the cooled joint with hot water and scrub it with a brush until no white film remains.
Can this flux be used with bronze or brass rods?
No, it is made for aluminium rod. For bronze rods, use the Sif Flux, a powder flux intended for bronze brazing work.
How should the powder be stored?
Keep the lid tight and store the pack in a dry place. The powder takes up moisture from damp air, which makes it cake in the pack and spit when it is heated.
