Abstract

The invention discloses an aluminum casting applicable to automobile manufacturing, which comprises the following components in percentage by weight: 0.5-3.5% of strontium, 0.01-2.0% of barium, 0.0003-0.005% of arsenium, 0.008-0.07% of boron, 0.00001-0.0005% of bismuth, 0.00001-0.0005% of rubidium, 0.0005-0.009% of lanthanide metal and the balance of aluminum and impurities. By manufacturing automobile parts from aluminum castings instead of iron castings, the weight of the automobile can be reduced, thereby achieving the goals of energy saving and fuel saving; and excellent hardness and toughness are beneficial to ensuring the quality of the casting and can enhance the functions of the automobile.

Description

technical field [0001] The invention relates to the field of aluminum castings, in particular to an aluminum casting used in automobile manufacturing. Background technique [0002] The history of using aluminum alloy instead of cast iron to produce auto parts can be traced back to the 1940s. At that time, a small number of automobile factories in Europe began to produce in small quantities. In the past 20 years, the application of aluminum castings in the world's automobile industry has been increasing, and in the total output of aluminum castings, a large part of aluminum castings are used in automobile manufacturing, making the production and application of aluminum castings in the world and the development of the automobile manufacturing industry A close connection has been made. [0003] Aluminum castings are rarely used in domestic automobiles. Moreover, the hardness and toughness of aluminum castings used in the automotive industry are not enough to achieve the effe...
