Brazing Opration |
The flux powder should be mixed with water to form a thick paste(mixing rate is 100g powder:35ml water).The paste should then be brushed onto the joint surfaces before brazing.Use a warm brazing rod dipped into flux.Suitable gap for joint is 0.01-0.05mm.Do not overheat the alloy and flux at local area,and heat gradually and evenly using a neutral flame |
Opration after Brazing | Any or all residue should be removed by hot water .Or it can be soaked in the citric acid |
Storage | Keep it in dry and cool place. Protect against damp, inedible |

The Silver brazing flux is actually a kind of flux preferably works with silver based brazing filler metal. It can also work very well with copper based filler metal. Some of the product on the list can also work with nickel based filler metal. The welding parts can be copper, copper alloy, steel, stainless steel, diamend, hard carbide.
There are several ways of dispensing the flux to the brazing joint. One can heat the filler metal (wire/strip) to about 400 degree C and dip the hot part into the flux powder. The powder will attached on the strop. Also, the flux can be used with brushes, and spry. Some of the product on the list can also be used as the core flux of flux cored brazing wire.
Another popular way of using the powder is to mix it with water to make paste and dispense the paste with brushes, althogh we highly recommend our customer to use flux paste instead.
TiBright has many kinds of product for different utility purposes. We also customerize our product for unique utilities. The following information can not exclusively cover all of our product. Please contact us for details and support.

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.)
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.
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.
Basically our package issue for powder product is for 500 gram/box, 20 box/carton. However, we have several special package for international customers: 20 gram/box, 225 gram/box, 400 gram /box. Small packages are popular for customers in repairment industry.
