Supply of silver solder paste solder paste silver silver silver solder paste solder flux

QJ305 silver brazing paste solvent is the latest successful development of a set all kinds of domestic and foreign advantages of the new silver solder brazing solvent, its fluidity and permeability are stronger than other similar flux. Use: with silver-based solder at 600-850 ℃ brazing copper and copper alloy, stainless steel, nickel alloys, tungsten carbide, diamond poly chips and other materials for flame resistance, induction, high frequency, moderate furnace variety of brazing. Physical state: paste, particle size ≤150μm, density 1.9-2.1 performance standards: JB / T6045-92 "hard brazing flux," the main ingredient: KF, KBF4, B2O3, composite fluoborate, complex borate active agents, such as water, non-prohibited substances. Features: Easy to use and stable performance, long-term storage of non-caking no precipitation, activity, mobility, smooth and clean weld, the weld residue is minimal. Technology is better than powdered flux, completely replace the similar foreign products. Applications: frames, refrigeration parts, compressors, stone tools, woodworking tools, auto parts, jewelry, electrical appliances, hardware tools, etc.
