The invention discloses a production process of an ultra-wide and ultra-thin aluminum alloy profile, which belongs to the technical field of aluminum alloy materials, and comprises the following steps: casting a liquid aluminum alloy into an aluminum alloy cast rod through the procedures of heat preservation, refining, slagging-off, degassing, filtering and the like, then carrying out homogenization treatment in a homogenization furnace, controlling the extrusion temperature, and extruding to obtain the ultra-wide and ultra-thin aluminum alloy profile. And then quenching, saw cutting, framing straightening and aging treatment are carried out, and the required product can be obtained. By means of a stable and continuous injection mode, melt metal forms a uniform solidification process in a crystallizer, defects such as bright grains, coarse grains, feather crystals, air holes and looseness can be eliminated, a compact and defect-free crystal structure is obtained, and the welding rod has the advantages of bein
