Abstract
A preparation method of a rapid bonding of a long silver-graphite electrical contact material and a solder strip material includes the following steps: first step, making a silver-graphite spindle into a silver-graphite electrical contact sheet material by an extrusion process; second step, performing a sintering to composite a solder strip material with the silver-graphite electrical contact sheet material to obtain a composite blank; and third step, performing a rolling and a heat treatment on the composite blank for one or more times to complete the composite of the long silver-graphite electrical contact material and the solder strip material. The method is a method for preparing a silver-based electrical contact material and solder composite material.
