The aluminum brazing flux has two main types: water soluble, and non-corrosive.
The water soluble aluminum flux has the contains that can absorb water from the air. It can mix with water to make paste, however, once mixed with water, the contains in the flux can get hydrolyzed and start loosing function. So the active life of this kind of aluminum flux after mixed with water is less than 4 hours. Our customers regulated the procedure that the flux must be used up after two hours after mixing with water. The life of the flux after expose to moist air is also limited.
Because of the solubility this kind of aluminum flux leaves no residual after being rinsed with water after brazing. However, the solution of this kind of flux is highly corrosive to metal materials thus the brazing parts need to rinsed thoroughly.
Another type is called non-corrosive aluminum flux. The most popular flux component is potassium floroaluminate (FB501). TiBright developed a new similar one with lower temeprature FB503. Also, FB502 has the main component of potassium-cesium floroaluminate. This one has low melting temperature (430C), and water soluble. It is also the most expensive one.
There is also a third type flux, FB504, which was developed by TiBright. FB504 has materials which can react with aluminum and generate a active layer on the surface of aluminum. This surface can act as filler metal, which means there is no need for any more filler metal.

Sometimes we need our customers to try different samples to make the perfect decision. Generally, we need to know the following information to choose a right product for you.
1. Materials of your parenting parts (to-be-brazed parts).
2. Heating methods. (eg. flame, induction, vacuum furnace etc. )
3. Atmosphere of application. (eg. room air, protective inert gas, reductive gas, vacuum, etc.)
4. Dimensions of your parts. Photos or graphs are preferred. (Different dimensions require different procedures.)
5. Current solution. (eg. brazing materials, equipment, procedures, etc.)
6. The reasons of searching new solution. (eg. price, strength, applicability, etc.)
7. Industry of your application. (Help us refer to similar examples.)
