The invention discloses a method and device for preparing alloy wires and bars through component-controllable friction stir extrusion, and belongs to the technical field of metal material machining.According to the scheme, firstly, wire raw materials of different materials are continuously fed through a material mixing device, and the wire raw materials pass through a gap between the bottom of a material crushing blade on a stirring body and the bottom of the material mixing device; the section of the bottom of the crushing blade can shear and crush the wire raw materials into granular materials, along with friction heat production of the stirring body, the crushed granular wire raw materials are continuously thermally plasticized and move upwards in the spiral direction of a spiral groove in the stirring body to be accumulated, the pressure of the material storage cavity is gradually increased, and the thermally plasticized wire raw materials are actively conveyed to the discharging hole. And finally, direct
