  • Business Information:

Product Feature:

Non-Corrosive HZ-QJ208 Aluminium Flux Powder and Paste for Brazing

We researched and developed independently HZ-QJ208non-corrosive aluminum brazing flux, which is better than other brand of aluminum brazing flux. HZ-QJ208 is aviable for gas shielded furnace and low-temperature flame with Al-Si eutectic brazing material. HZ-QJ202 is an ideal flux for furnace brazing of refrigerator, aluminum condenser, and aluminum radiator.


Use with zinc base or aluminum base brazing filler metals, for brazing aluminum alloy, aluminum-copper; aluminum-steel; aluminum-stainless steel in the method of auto torch flame brazing, hand flame brazing, furnace brazing, high frequence brazing and so on


K: 28-31

Al: 16-18

F: 49-53

Fe: 0.03 max

Ca: 0.2 max

H2O(550°C): 2.0max

Advantage and usage:

1. For pure aluminum, and Al-Mn alloys.

2. Smooth brazing surface, no blackening, and forming even membrane.

3. Non-corrosion and anti-oxidation.

4. No poisonous and no smelling

5. Environment-friendly.

6. No absorption and no aggregation for long time preservation.


Non corrosive aluminum brazing flux can be applied in torch brazing, furnace brazing, high frequency brazing, etc. The filler materials that work together with this flux can be powder, wires, rings or aluminum brazing sheet. Paste phase of this flux is more convenient for utility. Firstly, coat the paste flux onto the welding joint. In the flame brazing operation, quickly heat the flux to the temperature close to its melting point before adding the filler materials which will be heated to liquid phase and full fill the joint. After being so lidified, high strength welding joint can be formed. In furnace brazing, and high frequently brazing, the increasing rate of temperature and brazing temperature should be controlled carefully.

Note:The non- corrosive aluminum flux welding slag is hard to clear away, so it may not be cleared off.
