Embodiment Construction

[0018] Below in conjunction with embodiment the method of the present invention is further described.

[0019] An aluminum alloy automobile wheel hub and a preparation method thereof. The technical proposal lies in that the wheel hub is composed of aluminum ingots, silicon elements, magnesium elements, titanium elements, and strontium elements.

[0020] The specific implementation is as follows:

[0021] 1. Selection of aluminum ingots: select aluminum ingots for remelting with an aluminum content of ≤99.80% as raw materials for production.

[0022] 2. Raw material composition and ratio: aluminum ingot 98.835%, silicon element 0.7%, magnesium element 0.3%, titanium element 0.15%, strontium element 0.015%.

[0023] 3. Smelting: Add aluminum ingots into the melting furnace to melt to obtain aluminum solution, and then add the above-mentioned silicon, magnesium, titanium and strontium elements to the aluminum solution to obtain a mixed aluminum solution.

[0024] 4. Casting: Pr...

Abstract

The invention discloses an aluminum alloy automobile hub and a preparation method thereof. The aluminum alloy automobile hub concretely comprises an aluminum ingot, a silicon element, a magnesium element, a titanium element and a strontium element. The preparation method comprises the steps of fusing the aluminum ingot, then adding the silicon element, the magnesium element, the titanium element and the strontium element into an aluminum solution, and then, preparing a finished product of the automobile hub according to a conventional production process. Due to the implementation of the preparation method, the produced automobile hub product not only is beautiful in appearance, light in weight, good in strength and strong in heat radiation property, but also cannot rust forever and is very specific. In addition, the produced automobile hub product is low in production cost and very wide in market prospect.

Description

technical field [0001] The invention belongs to the technical field of manufacturing an automobile wheel hub, and in particular relates to an aluminum alloy automobile wheel hub and a preparation method thereof. technical background [0002] Wheel hub, English name: WheelHub, WheelHubUnit, a cylindrical metal part in a car tire centered on the shaft to support the tire. Important components for discs and half shafts. [0003] Automobile wheels are an important part of auto parts. With the growth of China's auto parts industry, the wheel industry has gradually grown. According to the data of "China's Automobile Wheel Industry Market Prospects and Investment Strategic Planning Analysis Report Prospects", since 2010, macroeconomic policies focusing on stimulating domestic demand have provided the foundation and guarantee for the steady development of the auto industry. Judging from the trend of the automobile market in 2010, the impact of macroeconomic policies on the automob...
