You can use silver -based solder and copper phosphorus brazing . The melting point of silver -based solder moderate, technology is good, and has good mechanical properties and thermal conductivity properties , is the most widely used hard solder . For applications requiring high conductivity of the workpiece to be elected with high silver content solder B-Ag70CuZn . Vacuum brazing or protective atmosphere furnace brazing, to be used free of volatile elements of the B-Ag50Cu, B-Ag60CuSn such as solder . Lower silver content solder , cheap, high temperature brazing , brazing toughness is poor, mainly used Aluminium Welding Rods  require lower copper and copper alloys . Silver copper phosphorus and copper-phosphorus brazing copper and copper alloys can be used for brazing , wherein the B-Cu93P has good fluidity, for electrical, instrumentation and manufacturing industries from shock loading of parts brazing, most suitable gap of 0.003 ~ 0.005mm. Copper-phosphorus silver brazing ( such as B-Cu70PAg) toughness and electrical conductivity than copper- phosphorus brazing good , mainly for high conductivity required electrical connections .
