FACTORY DIRECT SALE FREE SAMPLE ALUMINUM BRAZING FLUX WELDING POWDER BRAZING MATERIAL

HZ-QJ208 is a new kind of aluminium brazing flux matching aluminium base filler metal. It is widely used in brazing aluminium and aluminium alloy at the temperature of 558 to 620°C in the method of flame brazing, and furnace brazing. It can remove aluminium oxide effectively, and promote filler metal flowing and spreading in aluminium alloy. HZ-QJ208 is a common aluminium flux

Specifications:

1. For brazing aluminum and aluminum alloy

2. Remove aluminum oxide effectively

Physical properties:

Granularity:≤150μm

Density: 1.3-1.4

Standard: JB/T6045-92

Use method:

In advance, properly place the brazing filler metal on the brazing joint which will be heated together with the workpieces. In the process of manual torch brazing, firstly, the brazing wire need to be tipped with the flux. Then, after the work pieces are heated to the brazing temperature, the brazing wire is manually handled to keep close to the brazing joint. The wires are evenly heated by the outer flame from the Multiples holes brazing torch. To protect the metallic materials, the flame should be placed at the proper distance away from the wires to avoid the oxidation the work pieces, producing high quality brazing seams.
