Zusammenfassung:	The invention provides a 6xxx series aluminum alloy plate as well as a preparation method and application thereof. The 6xxx series aluminum alloy plate comprises Si, Mg, Mn, Cu, Zn, Cr, Fe, Ti, Al and inevitable impurities with specific contents in percentage by weight, and in the preparation process, an aluminum alloy cast ingot is subjected to two-stage homogenization treatment at a specific temperature within a specific time range, then the obtained homogenized cast ingot is subjected to hot rolling, cold rolling and solid solution treatment, and the 6xxx series aluminum alloy plate is obtained. And finally, the obtained solid solution plate is subjected to two-stage aging treatment at the specific temperature within the specific time range, and the 6xxx series aluminum alloy plate is obtained. Through a two-stage homogenization treatment system and a two-stage aging treatment system, the mechanical property and the forming property of the aluminum alloy plate are effectively improved, and when the aluminu
