Silver brazing flux

620-850

KBF4,KF,B2O3

Usages:

It 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 Celsius degree in flame brazing, resistance welding, high frequency brazing, furnace brazing.

Main purpose:

In 620-850℃ temperature range with silver based solder brazing of copper and copper alloy,carbon steel,stainless steel,hard alloy etcsilver brazing flux can meet the need of high technical requirements and programmable and automation

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, 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 operation, 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.
