The invention discloses an aluminum alloy magnetic air tightness window. The window comprises a window frame and left and right pushing/pulling window leaves arranged in the window frame, wherein contact surfaces between the left side edge of the left pushing/pulling wind leaf, the right side edge of the right pushing/pulling window leaf and the left and right inner sides of the window frame adopt magnetic straps to form mutual sucking tightness between the left and right pushing/pulling window leaves and the window frame. The window with the structure adopts the magnetic straps to replace wool tops, wherein the magnetic straps have the advantages of strong softness, difficult damage, difficult corrosion and easy cleaning, and the wool tops are easily damaged and polluted and difficultly cleaned; the window achieves better sealing effect by using the mutual sucking effect of the magnetic straps to realize the purposes of sound insulation and heat isolation; as the magnetic straps have strong softness, are difficultly corroded, are clean without smell, and have a long shelf life more than 10 years, the door and the window are easily cleaned and maintained, and are beautiful; for consumers, the window is a high cost performance selection of aluminum alloy window. Under the condition of overcoming the defects in the prior art, the window has skillful design, is easily applied, and is suitable for various doors and windows.
