| Abstract: | The development of AgRE/Cu/BAg composite contact material by means of cold rolling, diffusion annealing is discussed. It is found that by adding the proper amount of rare-earth elements and the fine grain metals in the silver base - the fine and stable grain can be obtained, and the sweating and corrosion resistance are improved. Here GBAg is the silver based welding material with 50% of Ag. The welding between the contact and the contact bridge can be done by covering a thin silver sheet on the copper base, with better weldability and higher productivity |
