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.

Application:

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
