The study on metal quantum wire mate- rials is the frontier field of the meso-physics field and has become the hot spot of the basic re- search and applied research. The fabrication methods of metal quantum wire materials in the do- mestic and overseas are reviewed, mainly including the mechanically controllable break junction （MCBJ） technique, electrochemical method, scanning tunneling microscopy （STM） method and so on. The applications of metal quantum wire materials are also introduced in detail. The main applications include the quantum conductance atomic switch, sensing applications and so on, and the important role of metal quantum wires in the study of quantum devices is emphasized. Final- ly, the problems of metal quantum wire materials are discussed, and the development direction of this field is also prospected. It is anticipated to arouse the research interesting of domestic re- searchers on quantum wire materials and promote the new developments in this field.
