Abstract

The invention discloses an aluminum alloy with a good friction-reducing property. The aluminum alloy with the good friction-reducing property is prepared with and comprises, by weight, the following components of 8.0-10.0% of silicon, 1.3-1.8% of copper, 0.4-0.6% of magnesium, 0.1-0.35% of manganese, 0.5-1.0% of indium, 0.1-0.35% of titanium and the balance aluminum and impurities. According to the aluminum alloy with the good friction-reducing property, alloying is conducted through addition of elements such as silicon, magnesium, manganese and the like so that strength of the aluminum-matrixmetal can be improved; and on this basis, a low-melting point element, indium is added, the friction-reducing effect of the matrix is improved, and thus the use requirements of liquid die-forged vortex disc products are satisfied.

Description

technical field [0001] The invention relates to the field of aluminum alloys, in particular to an aluminum alloy with good anti-friction performance. Background technique [0002] With the continuous development and progress of economy and technology, the lightweight development trend of the automobile industry is becoming more and more obvious. The development trend of automobile lightweight has put forward new requirements for the overall design and materials of automobiles. As the key component in the fourth-generation automotive air-conditioning compressor, the scroll disk is widely used in compressors for new energy vehicles and trucks due to its simple design and selection of aluminum alloy materials. [0003] Traditional scroll production mainly adopts gravity casting, low-pressure casting and forging processes. The materials selected in the above-mentioned processes are mostly cast aluminum alloys or deformed aluminum alloys of national standards, and the mechanical ...
