According to GB/T******2, we produced HZ-QJ**2 silver brazing powder. The powder could work together with silver based brazing alloys on copper and copper alloy, steel and stainless steel, and carbide steel, and PCD. 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-QJ**2 has characteristics of good fluidity, and fine powder. It is an ideal brazing flux.

Preparation: 

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

Operation: 

The flux powder can be preheated or mixed with water to smear on the work pieces. The proper gap distance should be controlled within the range of 0.***0.*5mm. Do not heat the flux and filler metal directly with frame. Heat gradually and evenly using a neutral flame.

Post treatment: 

The residue can be eliminated by merging the working pieces into hot water or *0% mass fraction citric acid.

Chemical composition: 

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

Usages: 

HZ-QJ**2 can work together with silver based brazing alloys for copper and copper alloy, stainless steel, nickel alloy, diamond PCDat the temperature range of **0 to **0 ℃ in flame brazing, resistance welding, high frequency brazing, furnace brazing.

Storage: Keep it in dry and cool place. Protect against damp, inedible.

Caution: 

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

2.Inesculent.

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

4.Do not mix it with other impurity materials.
