Silver Braze 65
Silver Braze 65 Technical
Silver Braze 65 is commonly used in the silver-smithing trade and other applications where their silver-white color is advantageous in color matching, and the corrosion resistance of high-silver, low-zinc alloy is desired. Silver Braze 65 is used in combination to perform sequential or step brazing of adjacent joints, to avoid re-melting the previously made joints. Because of their zinc content, Silver Braze 65 can be used to join iron and nickel-base alloys.
Silver Braze 65 is an intermediate silver brazing filler metal with a slight tendency to liquate (separation into low and high melting constituents) if heated slowly through its melting ranges. Silver Braze 65 is used for brazing silver base alloys, the re-melt temperature is raised by solution of silver in the brazing alloy. Conversely, the re-melt temperature of this brazing alloy is lowered by solution of copper when brazing copper base alloys. Flux is used with this alloy.
Properties of Brazed Joints
The properties of a brazed joint are dependent upon numerous factors including base metal properties, joint design, metallurgical interaction between the base metal and the filler metal.
