1.JN-HJ107 is a kind of smelting-type non-Mn mid-Si and mid-F flux.


2.Grain Size:10-60 (2.0-0.3mm) or 8-40 (2.5-0.45mm) meshes.


3.Current:direct current.


4.Performance:anti-porosity and anti-cracking.



1.Excellent clad layers can be gained when it is used in the build-up welding in conjunction with appropriate welding wires or solder strips, such as HOCr21Ni10 (AWS ER308), HOCr20Ni10Ti(AWS ER321), HOOCr21Ni10 (AWS ER308L), HOOCr24Nb, HOCr16Mn16.


2.for build-up welding of petrochemical equipments' corrosion-proof layers, stainless clad layers and pressure vessels. 


3.In conjunction with HOCr16Mn16, it can be used in the build-up welding of the track switch of high manganese steel (Mn13) and welding of Nb-contained stainless steel, etc.


Performance of Surfacing Layers :  

It can be used in the transition-layer welding in conjunction with HOOCr26Ni12 and in the build-up welding of 50mm-thick 18MnMoNb steel plate in conjunction with HOOCr21Ni10 as the surface-layer welding band.


Chemical Compositions: 


  AL2O3 +MnO




  TiO2 +SiO2






   S  P










  ≤ 10


 ≤ 0.05



 1. Flux must be baked for 2 hours under the temperature of 250~300°c before welding.  

 2. The iron rust, oil contamination and moisture on the weldment must be removed.

Q:What about the flux on the clothes?
You can use the sky to clean up the water. Shenzhen macro Electronics Co., Ltd. Alfa flux price advantage obvious, genuine guarantee
Q:Where will the industrial flux be sold?
Large electronic materials market
Q:What is a soldering flux? What does the solvent include?
There are borax, hydrochloric acid and so on
Q:The first electric iron, there are sponge, soldering flux, rosin, concrete how to use, why solder wire is also divided into different thickness of the electric iron, which can not be placed inside
With the same effect of rosin flux, the flux.The sponge is to clear the soldering liquid from the head of the iron
Q:180 degrees of high temperature solder line, what flux effect is good?
Can choose material flux, flux order, I suggest looking for experience in factory production flux, because it can reduce a lot of your time cost, but it can give you a lot about the flux selection and production advice.Now more and more advanced formula of flux, more and more environmentally friendly disposable, basically is the flux of environmental protection. On the one hand can improve welding performance, on the other hand, more environmentally friendly, but also to save manpower and material resources, but also more conducive to product sales.Personal advice:On the one hand, as long as you're not in remote areas, Tibet those words, I suggest you look for Huizhou (the chemical manufacturers), there is a flux manufacturers base. Can be delivered directly to the home, or through logistics!!
Q:Solder soldering for stainless steel. What is used as soldering flux?
Use stainless steel soldering fluid, the solder coating to be welded, and then use the ordinary tin tin can be welded.
Q:What is the soldering flux used for welding refrigerators?
The flux welding flux is automatically added to copper and silver flame welding flux. In the form of steam mixed gas, gas flux by means of flame, provide the fluxing action required, with solder at 620 DEG ~850 DEG in the temperature range of brazing of copper and copper alloy, carbon steel, stainless steel, metal melting effective surface oxide. To reduce the welding spot, keep the surface clean, contributing to solder spread,
Q:I use 10Mn2 welding wire with SJ101 flux for ring seam slam welding, the whole penetration crack, please ask whether the temperature is insufficient or what reason?
Your welding process record PRQ should be posted
Q:PcB board cleaning, no cleaning flux, after peak, how can clean?
After welding, usually with DT-78A or DT-68A to clean, these two cleaning agents in the electronic plate cleaning is generally relatively clean, and manual cleaning, pay attention to the direction of the product.The flux is in the process of welding to welding and insulation effect of the welding flux in the later, and no clean flux is not only to help, and after welding surface clean, no special requirements without flux plate washing.Advantages of no cleaning flux:1., good weldability, solder joints are full, no welding beads, bridges and other undesirable2. non-toxic, no pollution to the environment, safe operation3. after welding, the board surface is dry, non corrosive and non stick4. after welding, on-line testing ability5. match the material of SMD and PCB board6. after welding there is a specified surface insulation resistance value (SIR)7. adapt to welding process (dip, spray coating, foam, etc.
Q:What kind of soldering flux is used to weld copper and copper wire by spot welding machine?
Ultrasonic welding machine, without soldering flux, find it yourself
