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 °C in flame brazing, resistance welding, highfrequencybrazing, furnace brazing.

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, 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.
