High-performance aluminum alloy battery tray and preparation method thereof

Abstract

According to the high-performance aluminum alloy battery tray and the preparation method thereof, by optimizing the chemical components and the proportion of the aluminum alloy battery tray, the aluminum alloy battery tray which is uniform in structure form and small in grain size can be obtained, Sr, Ce, Zr and Y elements are added at the same time, air holes generated in a melt can be inhibited, and the high-performance aluminum alloy battery tray is obtained. And the melt can be subjected to modification treatment, so that the mechanical property is remarkably improved. Besides, after process optimization, after ultrasonic vibration treatment and under the action of ultrasonic cavitation, the quality of melt is improved, then the tensile strength of the aluminum alloy battery tray is remarkably improved, after ultrasonic vibration treatment, the alpha-Al grain size is reduced, eutectic silicon distribution is more uniform, the fracture surface is completely covered with uniform and fine dimple, and the tensile strength of the aluminum alloy battery tray is improved. And the tensile strength is further enhanced. And the aluminum alloy battery tray with excellent mechanical properties can be obtained on the whole.
