Abstract
The effect of palladium on structure, melting ranges and technological properties of alloys of the Ag-Cu-Zn-Ni-Mn system was investigated. It was established that alloying with palladium allows improving strength properties of the brazed joints at an insignificant decrease of the contact angle.
 
 
Keywords: brazing, diamond-hard alloy tool, cadmium-free filler alloys, structure, melting range, contact angle, induction heating, phase transformation temperature, palladium, silver filler alloy, strength of joints
