Silver Brazing/Welding Flux Powder/Paste

1.Stable chemically and physically 2.No precipitate

Huazhong Welding Material Manufacturing Co.,Ltd is a leading supplier of superior quality of Brazing Flux. Brazing Flux is a substance, which cleans the metals when they are joining while soldering, brazing, and welding. In high-temperature metal joining processes, the primary purpose of flux is to prevent oxidation of the base and filler materials. Secondarily, Brazing Flux acts as a wetting agent in the soldering process, reducing the surface tension of the molten solder and causing it to better wet out the parts to be joined. Additionally, flux allows solder to flow easily on the work piece.

5.Reducing the surface tension of the molten solder and causing it to better wet out the parts to be joined

6.Allows solder to flow easily on the work piece

Silver Brazing paste

Featuring better fluidity and permeability than other silver brazing pastes, HZ-QJ305 silver brazing paste is a new type of brazing flux researched by Huazhong, which gathering advantages from all kind of welding flux.

Usages: HZ-QJ305 can work together with silver-based brazing alloys for copper and copper alloys, stainless steel, nickel alloys, diamond PCD at the temperature range of 600 to 850 °C in flame brazing, resistance welding, high-frequency brazing, furnace brazing.

Physical status: paste  Granularity:≤150μm   Density: 1.9-2.1   Standard: JB/T6045-92

Chemical composition: complex borate, complex fluoborate, activities, water etc. No contain restricted compounds.

Characters: The flux is very stable chemically and physically. No precipitate, caking or loss of activity and fluidity for long time storage. Featuring smooth surface and small welding seam, HZ-QJ305 can replace similar foreign product. 

Application areas: Refrigerator accessories, compressor, stone and wood cutter, automobile accessories, glass frame, ornament and jewelry, electric apparatus, hardware tools, etc.

Preparation: To optimize the result, the work pieces should be cleansed thoroughly previous to brazing operatation, the surface should not be too rough or attached on metallic particle or dirt. Stainless steel work piece should not be scrubbed by steel wire brush.

Operation: Dip the work pieces into the paste or diluted paste before brazing.

Post treatment: the residue can be eliminated by merging the work piece into hot water on 10% mass fraction citric acid.

Caution: inesculent. Immediate water flashing is need if it is splashed into eye or mouth. Do not mix it with other impurity materials. After the packing is opened, the paste can be hardened easily.  

 Silver Brazing Powder

According to GB/T6045-92, Huazhong produced HZ-QJ102 silver brazing powder. The powder could work together with brazing alloys on copper and copper alloy, steel and stainless steel, and carbide steel. It could dissolve oxides on the surface of metal more quickly and effectively, promote flow distribution of alloy, and improve the purity and strength of brazing.

Characters: HZ-QJ102 has characteristics of good fluidity, and fine powder. It is an ideal brazing flux.

Chemical composition: complex borate, complex fluoborate, activities, water etc. No contain restricted compounds.

Usages: HZ-QJ102 can work together with silver-based brazing alloys for copper and copper alloy, stainless steel, nickel alloy, diamond PCD at the temperature range of 550 to 850 °C in flame brazing, resistance welding, high-frequency brazing, furnace brazing.

Caution: 1.To optimize the result, the work pieces should be cleansed thoroughly previous to brazing operations.

        2.Keep it in dry and cool place, and protect against damp. 

        3.Inesculent.

        4.Immediate water flashing is need if it is splashed into eye or mouth. 

        5.Do not mix it with other impurity materials.
