Good fluidity,strong ability in removing oxidation film.Can be mixed with water to become paste,with good viscosity. Water soluble, no residual left. Recommend for radiator brazing.



Best activity for brazing with AlSi12, 4047 filler metal for the best brazing quality the requirements.  Water soluble, no residule left. Highly recommend for radiator, bike producer. 



Great activity with AlSi12, 4047 filler metal alloy.  water soluble, no residule left. Highly recommend for situation of high requirements in powder or paste form.



Superior ability in removing oxidation film. Potassium fluoroaluminate flux system. Non-water-soluble. Thin residual film remain. Recommend for auto-radiator furnace brazing procedure. 



Superior ability in removing oxidation film. Low melting temperature, water washable. Expensive materials with cesium.  Recommend for auto-radiator furnace brazing procedure. 



Great activity, low temperature, non-water soluble, thin residual film remain, in powder or paste form.



Self flux and no filler metal is needed. Non-water soluble, thin residual film remain, in powder or paste form. 







           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 fluoroaluminate (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.

Buying Guides

        Yantai Tibright Welding Materials Co. Ltd. is a manufacturer of all kinds brazing materials, equipments, and utensils. The company has started since 2000. We are the most professional researcher and developer of brazing materials in China. We have accumulated dozens of different product technology and abundant product pool. We are also glad to customize product for specific customers. 
         When choose from our product pool, please check out our recommended product list and if you have any questions, please let us know and we will try our best to satisfy your inquiry. Sometimes we need our customers to try different sample to make the perfect decision. Generally, we need to know the following information to choose a right product for you. 

1. Materials of your to-be-brazed parts. 

2. Heat method. (eg. flame, induction, vacuum furnace etc. )

3. Dimensions of your parts, photoes or graphes are preferred. (Different dimensions requires different procesure.)

4. If available, what kind of brazing materials are currently being used. 

5. What industry you are in. (help us refer to similar samples.)





Company Information

         Yantai Tibright Welding Materials Co. Ltd. (Chinese name, Guguang) was started from laboratory in 1996 and founded in 2000. The company is the first one who specialized on brazing materials in China, which means we did not have much foundations, and the pioneers of the company started product formulars from very basic researches. Ever since then, Tibright have had all product developed by ourselves.

          As we focus on brazing materials, our main product is brazing fluxes, brazing alloys, self flux brazing alloys, brazing alloy paste, and brazing materials. We make brazing alloys with main compositions of silver, copper, aluminum, nickel, chromium, zinc, tin, mangenese. We make fluxes and binder agents for these alloys. 

          Since 2010, our research has been specially on the brazing alloy powder and paste as well as the self flux alloys, such as flux coated wire and rings, flux cored wire and rings and flux added alloy paste. 

            In the year 2015,  TiBright's was asked to be the first draftsman of the industry standard of China "JB 6045-2015 The FLux For Brazing" and attended the drafting work of many standards as expertise. So far we have authoized 15 patents. 

          Our main current customers are in dozens of different fields, such as radiator, compressor, electic utility, glasses, auto parts, tools, nuclear station, and so on. Our big customers include Haier, Gree, Media, Siemens, Sanhua, and so on.



Our Services

        One highlight of our service is that we provide customized product specially designed for specific customer. We have a lot of successful cases in which the customer had the product suitable for their own procedure, environment and operation habits perfectly.

        We also provide entire brazing solution for customers to solve all the problems related to brazing process. For those brazing parts, materials and dimensions which are hard to braze we can come up with a solution after enough research for our customers.

        About sixty percent of our equipments are designed and crafted in our own machine workshop. We also produce the service of special designed brazing tools and machines. We have the ability to reserch product together with our customers.
