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:How do you remove the soldering flux on the PCB circuit board? The use of absolute ethyl alcohol is useless
It's OK to have a dip in a liquid paraffin
Q:What is the brazing flux
The solder is usually borax. Clean the weld before welding to avoid grease sticking.
Q:Can aluminum solder be used without soldering flux?
There are a lot of aluminum tin answers online, but can not fundamentally solve the problem of aluminum oxide at. Is not high enough to solder iron temperature, there are non professionals that use direct welding method and rosin, the most close to the aluminum solder is using flux solder, also provide pictures to prove how good the effect of solder, flux is actually used to weld several months before solder oxidation quality directly effect of aluminum products.No soldering flux, no flux, no harmful gas, and a clean working environment. The utility model can effectively prevent bubbles and pinholes, does not need cleaning procedures after welding, reduces the bad rate, reduces the welding time and improves the welding quality.Penetration soldering aluminum to improve sealing.
Q:What are the hazards of soldering flux?
Which is so serious? Let me show you the authoritative informationI've been doing this for ten years and I don't see any problemsWhen exposed to gas inhalation may cause dyspnea, dizziness, weakness, fatigue, nausea, headache and other symptoms. Pain reactions may be delayed for several hours.Constant exposure to the skin can cause tingling, skin wrinkling and dermatitis
Q:How to use soldering flux
Tin welding circuit is the key, is to clean the welding parts, rosin heating and melting at the welding position or the flux on welded objects, and then eat tin in iron after welding to the point above it.In general, soldering small parts with rosin, welding large parts with soldering flux. Rosin is used on the circuit board and soldering flux for single piece welding.
Q:Flux and residue problems
Look at your soldering flux type and content. Should the alcohol base be better?
Q:What component of a soldering flux conducts electricity?
It is the main component of solder paste
Q:How to increase the fluidity of flux?
Add more thinners
Q:How about the soldering flux with the same side?
The same side of the flux is only moderate, before the company is with the solid content is not too high, generally do not have to worry about the flux will cause adverse consequences, the control is safe in the following 60ML/MINIn welding, compared with foreign flux, a little bit worse, usually a little more than tin, see what you do products
Q:What happens if the soldering flux splashes into the eye?
1: first wash your eyes with clean water immediately, because the flux is a corrosive action, so you must clean it immediately.2: you wash it after all inside than hospital doctors in their own professional, so you continue to wash your eyes at the same time, if you are afraid of time than the general hospital also can choose door-to-door service, you put the basic situation and the doctor said clearly after the doctor will take a special tool to help you get to get inside the eye to go, after all, is not a small problem, to be serious
