Description

technical field [0001] The invention relates to the technical field of automobile wheels, in particular to an automobile aluminum alloy wheel hub with high temperature resistance and corrosion resistance. Background technique [0002] Wheel hub, English name: Car Rim, the cylindrical metal part in the car tire centered on the shaft to support the tire. In layman's terms, it is the part where the axle is installed in the center of the wheel, which is connected to the brake drum (brake disc), wheel disc And important parts of the half shaft. [0003] The wheels on the market can be divided into steel wheels and alloy wheels according to the material, and each has its own advantages and disadvantages. [0004] The main advantage of steel wheels is that the manufacturing process is simple (casting process is generally used, such as aluminum alloy wheels are generally produced by low-pressure casting process), the cost is relatively low, and the ability to resist metal fatigue i...
