Silver brazing fillers are the most frequently used precious-metal fillers. They are suitable for brazing nearly all steels and nonferrous metals except aluminum, magnesium, and titanium. Chemical compounds Between 25 and 40 percent of industrial silver is consumed in the production of the photosensitive chemicals silver chloride and silver bromide. These silver salts are prepared by adding sodium chloride or sodium bromide to a very pure solution of silver nitrate. The highly insoluble silver chloride or silver bromide then precipitates from solution.
