METHOD FOR PRESSING PLATE AU ALLOY BRAZING FILLER METAL HAVING LOW MELTING POINT

摘要

PURPOSE:To obtain pressed brazing filler metal free from chipping and cracking by preheating a plate Au alloy brazing filler metal having a low melting-point, sending the material successively to a press die providing a heating and heat- insulating part and pressed it at a specified temperature. CONSTITUTION:Bar stock 3 of plate Au alloy brazing filler-metal having a low melting-point such as Au-Sn, Au-Ga is preheated at a preheating part 1. Then, that material (bar stock 3) is sent successively to the press die providing the heating and heat-insulating part 5 and pressed in the range of 50-320 deg.C. In this way, the die can be improved in durability.
