Sif Flux Manufacturer,Supplier and Exporter in India
Product Code : EL-MWLE-13068
Jlab Export is a leading Sif Flux Manufacturer,and suppliers in India
Bronze brazing joins steel, cast iron, copper and brass with a bronze filler rod at a lower heat than fusion welding. It needs a flux to keep the joint clean. This silicon-bronze flux is a powder made for bronze rod, packed in 500 g. It dissolves oxides on the hot metal so the bronze can run and bond.

Bronze Welding Practicals with Gas Plant
Welder trainees use the Gas Welding Plant to braze-weld two mild steel plates with a bronze Brazing Rod. The plates are bevelled, cleaned and heated to a dull red. The warm rod tip is dipped into the flux, which clings to it. The rod is then melted onto the joint, so the bronze tins the steel before the run is built up.
Teachers can also show a repair to a cracked cast iron part, where bronze welding avoids the cracking that full fusion welding can cause. Students set the flame slightly oxidising, which reduces fuming from zinc-bearing bronze rods, and wear Gas Welding Goggles throughout.
Frequently Asked Questions
How is a powder flux used with a bronze rod?
Warm the rod tip in the flame and press it into the powder so it picks up a fused coat. A light sprinkle on the heated joint helps the first run of bronze wet the metal. Recoat the rod whenever that coat is used up.
Which metals can be joined with bronze rod and this flux?
Bronze brazing suits mild steel, cast iron, copper and brass, and it can join two different metals from that list. It is not used on aluminium, which needs its own rod and the Flux made for aluminium rod.
Do phosphor-copper rods need this flux?
Not on copper-to-copper joints, where phosphor-copper rods flux themselves. On brass they do need a flux, normally one made for silver and phosphor-copper brazing. This flux is meant for bronze rods.
How is the residue removed?
Bronze brazing flux leaves a hard, glassy residue. Chip and wire-brush it off once the joint has cooled, then wash the area, because traces left on the metal can attract moisture.
