Abstract
PURPOSE: To obtain an electrical contact material having both characteristics of alloy powder and alloy granules by dropping a molten Ag alloy into a gas from nozzle holes, solidifying it in a liq. in the form of a disk, and subjecting the resulting disks to internal oxidation, compression and sintering.
CONSTITUTION: A molten Ag alloy 2 in a melting crucible 1 is dropped into the air from a plurality of holes 6 of a nozzle 4, received in a cooling tank 5 filled with water or the like, and solidified in the form of a flat disk. The resulting disks are internally oxidized, cold compressed, and sintered to obtain an electrical contact material. By this method alloy granules of an arbitrary shape can be formed in accordance with the oxidation progress speed of the Ag alloy for internal oxidation, and the production efficiency is enhanced considerably.
