Xiaomi Auto and Shanghai Jiao Tong University Apply for Patent on Die-Cast Magnesium Alloy for Automotive Components

According to information from the National Intellectual Property Administration, Xiaomi Automobile Technology Co., Ltd. and Shanghai Jiao Tong University applied for a patent titled "A Die-Cast Magnesium Alloy, Its Preparation Method, and Automotive Structural Components," with the publication number CN119843127A and an application date of December 2024.

The patent abstract reveals that the disclosure relates to a die-cast magnesium alloy, its preparation method, and automotive structural components. Based on the total weight of the die-cast magnesium alloy, it comprises: 5~7 wt% Al, 7~12 wt% La, 0.2~0.4 wt% Mn, impurities below 0.3 wt%, and the balance being Mg. The ratio of Al to La content is 0.50~0.75. This disclosure provides a magnesium alloy that simultaneously balances cost, high strength, and heat-resistant creep properties, expanding the application of die-cast magnesium alloys in high-strength, heat-resistant parts.
