A method of preparing silver-based oxide electrical contact materials with fiber-like arrangement, includes the following steps of: (1) uniformly mixing the silver-metal alloy powders and graphite powders and then ball-milling; (2) internally oxidizing the ball-milled powders; (3) sieving; (4) placing the sieved powders and the matrix powders into the powder mixer for mixing; (5) cold-isostatically pressing; (6) sintering; (7) hot-pressing; and (8) hot-extruding, thereby obtaining the silver-based oxide electrical contact material with fiber-like arrangement. The method of the present invention can obtain the silver-based oxide electrical contact material having neat fiber-like arrangement with no specific requirement on processing deformation, plasticity and ductility of the reinforcing phase. The production process in this method is simple and is easy to operate. Besides, there is no particular requirement on the equipment. The method greatly improves the performance of contact materials in aspects of resistance to welding and arc erosion, conductivity, and processing performance.
