HZ-Ag25B BRAZING FILLER MTAL

HUAZHONG HZ-Ag25B Alloy is a high melting point cadmium free silver brazing filler metal. It has a high melting temperature (700 to 790°C) with a quoted melting range of 90°C. This melting range suggests medium to sluggish flow properties when molten. The high brazing temperature of the filler metal makes it less easy to use than the high silver content alloys. Optimum joint gaps at brazing temperature are 0.075-0.2mm

Product uses: 

HZ-Ag25B can be used to join most common engineering metals - copper, copper alloys including, brasses, bronzes, gun metal, nickel silver, aluminum bronze, copper nickel, steels including, mild, carbon, tool steel, stainless steels, low alloy steel. This alloy is not normally recommended for brazing tungsten carbide and PCD segments where lower  melting or nickel / manganese containing silver brazing filler metals are often preferred.
