Hz-qj305 100g Silver Solder Paste

Keeping in mind ever-evolving requirements of our respected clients, we are manufacturing, exporting and supplying a wide range of HZ-QJ305 100G Silver Solder Paste in China, Nuevo Leon, Mexico. Clients can buy these products from us at very nominal rates.

Features :-
Cleans the metals when they are joining while brazing and welding
High-temperature metal joining processes
Prevent oxidation of the base and filler materials
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
Allows solder to flow easily on the work piece

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

Usages: HZ-QJ305 can work together with silverbased brazing alloysfor copper and copper alloys, stainless steel, nickel alloys, diamond PCD at the temperature range of 600 to 850 A C in flame brazing, resistance welding, highfrequencybrazing, furnace brazing.

Physical status : paste
Granularity : a 150I m
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 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.
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.
