The invention discloses an aluminum-palladium bimetallic wire as well as a preparation method and application thereof, and relates to the technical field of preparation of blasting materials. Comprising the following steps: preparing an aluminum rod by adopting a continuous directional solidification method, drawing the aluminum rod to obtain an aluminum wire, chemically electroplating the aluminum wire in a palladium-containing medium to obtain a palladium-plated aluminum wire, and carrying out cold drawing on the palladium-plated aluminum wire. The aluminum rod is subjected to wire drawing to obtain the aluminum wire, then the aluminum wire is subjected to chemical electroplating in the palladium-containing medium, the obtained palladium-plated aluminum wire is subjected to cold drawing, compared with the prior art, the production process is obviously shortened, the aluminum-palladium bimetal wire can be more efficiently prepared, and the production process can be suitable for large-scale industrial product
