Problems solved by technology

However, the problem is that the cost is high and the process is complicated. At the same time, because the composition contains tantalum, it is very easy to oxidize when preparing the aluminum alloy wheel hub.
However, none of the above methods can effectively control the composition segregation of the aluminum alloy during the casting process, which eventually leads to poor performance of the aluminum alloy wheel hub and prone to local defects.

Abstract

The invention belongs to the field of automobile hubs, and particularly relates to an aluminum alloy material used for a hub and a casting method. The aluminum alloy material is prepared from, by mass percent, 5%-8% of silicon, 3%-8% of magnesium, 0.01%-0.03% of copper, 0.01%-0.02% of zinc, 3%-5% of manganese, 1%-6% of titanium, 0.5%-3% of chromium, 10%-12% of tetrapod-like zinc oxide, 1%-5% of magnesium salt crystal whiskers and the balance aluminum. By means of the aluminum alloy material and the casting method, the comprehensive mechanical property of the aluminum alloy hub is effectively improved, and the prepared aluminum alloy hub is uniform in component and free of local defects.

Description

technical field [0001] The invention belongs to the field of automobile wheel hubs, in particular to an aluminum alloy material and a casting method for the wheel hubs. Background technique [0002] Aluminum alloy wheels have the advantages of light weight, energy saving, low price, high surface quality, good heat dissipation, easy molding and good vibration damping performance, etc., and are widely used in the automotive field. However, with the rapid development of the automobile industry, the performance requirements for aluminum alloy wheels are also continuously increasing. There are still some problems in the existing aluminum alloy wheels, such as insufficient strength, heavy weight, poor processing performance, poor heat dissipation, and limited deterioration treatment effect. , Unstable quality of castings and other issues, therefore, it is necessary to further improve the comprehensive performance of aluminum alloys for wheel hubs. [0003] In order to solve the a...
