HUAZHONG HZ-Ag25BSn is a high melting point cadmium free silver brazing filler metal. It has a high melting temperature (700 to 800°C) with a quoted melting range of 100°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
Factory No: HZ-Ag25BSn
AWS:BAg-37
Chemical elements(%):25 Ag, 40 Cu, 33 Zn, 2 Sn
Solidus: 700°C
Liquidus: 800°C
Processing Temp.:800-890°C
Density:4.62
Color:Light Yellow
Specifics and Use:
1.Least silver of the Ag-Cu-Zn-Sn family
2.Moderate ductility limits joint design and application
It 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.
Conditions for use: It is designed for brazing in air with the use of a flux. Generally it is necessary to use a flux with a higher working rang. However on small components and with rapid heating cycles a general-purpose flux may be acceptable.
