HZ-QJ202 non-corrosive aluminium brazing flux
We researched and developed independently HZ-QJ202 non-corrosive aluminium brazing flux, which is better than other brand of aluminium brazing flux. QJ202 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, aluminium condenser, and aluminium radiator.
Physical description: white powder and paste. Density(20°C):2.8g/cm3

Advantage and usage:
1. For pure aluminium, 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.
Operation: Non-corrosive aluminium 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 aluminium 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.
Package: 250g/box, 500g/box, 20kg/carton, 25kg/carton, 30kg/drum, 40kg/carton,
P.S. The melting temperature of HZ-QJ202 non-corrosive aluminium brazing flux is narrow, about 550°C.
