摘要： A lightweight automobile brake disc (10) and a preparation method therefor. A disc cap (110) of the lightweight automobile brake disc (10) is prepared from a first aluminum-based material with good processibility, and a disc body (120) is prepared from a second aluminum-based material with good wear resistance and heat resistance. By controlling the alloy element content of an aluminum alloy matrix in the first aluminum-based material to be smaller than or equal to the alloy element content of an aluminum alloy matrix in the second aluminum-based material, the sintering shrinking percentages of the two materials during a preparation process, in which a powder metallurgy method is used, are matched, and defects such as cracking does not occur during the preparation process. In addition, the thermal expansion coefficients of the two materials under the service working conditions of the automobile brake disc are also matched, such that the disc cap (110) and the disc body (120) are only metallurgically connected in a circumferential direction, that is, a higher interface bonding strength can be obtained. Moreover, brake performance requirements, such as friction wear and fatigue resistance, required by a traditional automobile brake disc (10) during the friction braking process are satisfied.
